Bis[μ-2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-κ(4) N (2),N (3):N (4),N (5)]bis-[(nitrato-κO)silver(I)] tetra-hydrate.

ABSTRACT: The self-assembly of an angular 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligand (L) with silver nitrate (AgNO3) produced a new dinuclear silver(I) coordination complex, [Ag2(C12H8N4S)2(NO3)2]·4H2O, which crystallizes with two Ag atoms bridged by two L ligands. The Ag atom is surrounded by four N atoms of L and by one O from the nitrate anion defining a distorted square pyramid. The atoms comprising the dication are nearly coplanar, with an r.m.s. deviation of 0.1997 Å. Mol-ecules are linked by C-H⋯O and O-H⋯O hydrogen bonds through nitrate anions and water mol-ecules, forming a two-dimensional porous network. The overall structure involves stacking of Ag complex layers along the b axis. The cohesion in the three-dimensional architecture is ensured by O⋯Ag inter-actions.

trans-Bis[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-κ(2) N (2),N (3)]bis-(methanol-κO)iron(II) bis-(perchlorate).

Project description:The title compound, [Fe(C12H8N4S)2(CH3OH)2](ClO4)2, crystallized in the solvent-free form from a methanol solution. The Fe(II) ion is located on a centre of inversion. The distorted N4O2 octa-hedral coordination geometry is formed by two N,N'-chelating equatorial 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands and axially coordinating methanol coligands, resulting in the mononuclear trans-(N (2),N (3),O)2 coordination mode. The methanol co-ligand is involved in a hydrogen bond to the perchlorate counter-ion.

trans-Diaqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole]cobalt(II) bis-(tetra-fluoridoborate).

Project description:The bidentate 1,3,4-thia-diazole ligand substituted by two 2-pyridyl rings (denoted L) has been found to produce the new monomeric title complex, [Co(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The thia-diazole and pyridyl rings surrounding the Co atom are almost coplanar [dihedral angle = 4.35?(7)°]. The mean plane defined by these heterocyclic moieties makes a dihedral angle of 18.72?(6)° with the non-coordinated pyridyl ring. The Co(2+) cation, located at a crystallographic center of symmetry, is bonded to two ligands and two water mol-ecules in a trans configuration in an octa-hedral environment. The tetra-fluorido--borate ions can be regarded as free anions in the crystal lattice. Nevertheless, they are involved in an infinite two-dimensional network along the [010] and [101] directions of O-H?F hydrogen bonds.

trans-Diaqua-bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole]nickel(II) bis-(tetra-fluoridoborate).

Project description:The bidentate 1,3,4-thia-diazole ligand, namely, 2,5-bis-(2-pyrid-yl)-1,3,4-thia-diazole (denoted L), untested as a polydentate ligand, has been found to form the monomeric title complex, [Ni(C(12)H(8)N(4)S)(2)(H(2)O)(2)](BF(4))(2). The complex shows an octa-hedral environment of the nickel cation in which the Ni(2+) ion is located on a center of symmetry, linked to two ligands and two water molecules. In this 1:2 complex (one metal for two organic ligands) each thia-diazole ligand uses one pyridyl and one thia-diazole N atom for chelate binding. In the second pyridyl substituent, the N atom is oriented towards the same direction as the S atom of the 1,3,4-thiadiazole ring. The mean plane of the thia-diazole and pyridyl rings linked to the nickel cation forms a dihedral angle with the other pyridine ring of 18.63 (8)°. The tetra-fluorido-borate ions can be regarded as free anions in the crystal lattice. Nevertheless, they are involved in an infinite two-dimensional network parallel to ([Formula: see text]01) through O-H⋯F hydrogen bonds.

Crystal structure of bis-(azido-κN)bis[2,5-bis(pyridin-2-yl)-1,3,4-thia-diazole-κ(2) N (2),N (3)]cobalt(II).

Project description:In the mononuclear title complex, [Co(N3)2(C12H8N4S)2], the cobalt(II) atom is located on an inversion centre and displays an axially weakly compressed octa-hedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands, whereas the axial positions are occupied by N atoms of the azide anions. The thia-diazole and pyridine rings linked to the metal are almost coplanar, with a maximum deviation from the mean plane of 0.0273 (16) Å. The cohesion of the crystal is ensured by weak C-H⋯N hydrogen bonds and by π-π inter-actions between pyridine rings [inter-centroid distance = 3.6356 (11) Å], forming a layered arrangement parallel to (001). The structure of the title compound is isotypic with that of the analogous nickel(II) complex [Laachir et al. (2013 ▶). Acta Cryst. E69, m351-m352].

Crystal structure of bis-(azido-κN)bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-κ(2) N (2),N (3)]nickel(II).

Project description:Reaction of 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole and sodium azide with nickel(II) triflate yielded the mononuclear title complex, [Ni(N3)2(C12H8N4S)2]. The Ni(II) ion is located on a centre of symmetry and is octa-hedrally coordinated by four N atoms of the two bidentate heterocyclic ligands in the equatorial plane. The axial positions are occupied by the N atoms of two almost linear azide ions [N-N-N = 178.8 (2)°]. The thia-diazole and pyridine rings of the heterocyclic ligand are almost coplanar, with a maximum deviation from the mean plane of 0.0802 (9) Å. The cohesion of the crystal structure is ensured by π-π inter-actions between parallel pyridine rings of neighbouring mol-ecules [centroid-to-centroid distance = 3.6413 (14) Å], leading to a layered arrangement of the mol-ecules parallel to (001).

Crystal structure of bis-[2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole-κ(2) N (2),N (3)]bis-(thio-cyanato-κS)copper(II).

Project description:The mononuclear title complex, [Cu(SCN)2(C12H8N4S)2], was obtained by the reaction of 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole and potassium thio-cyanate with copper(II) chloride dihydrate. The copper cation lies on an inversion centre and displays an elongated octa-hedral coordination geometry. The equatorial positions are occupied by the N atoms of two 2,5-bis-(pyridin-2-yl)-1,3,4-thia-diazole ligands, whereas the axial positions are occupied by the S atoms of two thio-cyanate anions. The thia-diazole and the pyridyl rings linked to the metal are approximately coplanar, with a maximum deviation from the mean plane of 0.190 (2) Å. The cohesion of the crystal structure is ensured by weak C-H⋯N hydrogen bonds and π-π inter-actions between parallel pyridyl rings of neighbouring mol-ecules [centroid-to-centroid distance = 3.663 (2) Å], leading to a three-dimensional network.

Project description:The complete mol-ecule of the title compound, C(16)H(12)Cl(2)N(2)S(3), is generated by crystallographic twofold symmetry, with the S atom of the thiadiazole ring lying on the rotation axis. The dihedral angle between the mean planes of the 1,3,4-thia-diazole and benzene rings is 87.19 (7)°. In the crystal, mol-ecules are linked by C-H⋯N inter-actions and short S⋯S contacts [3.3389 (9) Å] occur.

catena-Poly[[bis-(nitrato-κO,O')copper(II)]-μ-2,2'-(ethane-1,2-diyldithio)di-1,3,4-thia-diazole-κN:N].

Project description:In the title compound, [Cu(NO(3))(2)(C(6)H(6)N(4)S(4))](n), the Cu(II) atom, occupying a crystallographic inversion centre, is six-coordinated by two N atoms of two 2,2'-[1,2-ethane-diyl-bis-(thio)]bis-[1,3,4-thia-diazole] ligands in trans positions, and four O atoms from two symmetry-related opposite nitrate anions, which are asymmetrically bonded, resulting in a strong distorted octa-hedral geometry of the central atom. The ethane group is equally disordered over two sites via another inversion centre. The bridging bidentate 2,2'-[1,2-ethanediylbis(thio)]bis-[1,3,4-thia-diazole] ligands link the Cu(II) centres into a one-dimensional chain. The chains are inter-connected via inter-molecular S⋯O inter-actions [3.044 (4) and 3.084 (5) Å] and weak C-H⋯O hydrogen bonds, generating a three-dimensional supra-molecular structure.

Project description:The title mol-ecule, C(18)H(12)N(4)S(3), consists of three essentially planar fragments, viz. two methyl-substituted benzonitrile rings and a substituted thia-diazole ring. The dihedral angles between the substituted benzonitrile rings and the central thia-diazole ring are 28.29 (10) and 78.83 (6)°, and the dihedral angle between the two benzonitrile rings is 72.89 (7)°.

2,2'-[(1,3,4-Thia-diazole-2,5-di-yl)bis-(sulfanedi-yl)]diaceto-nitrile.

Project description:In the title compound, C6H4N4S3, the 1,3,4-thia-diazole ring is essentially planar, with an r.m.s. deviation of 0.001 Å. The two N-C-S-C torsion angles in the mol-ecule are -23.41 (15) and 0.62 (14)°. One aceto-nitrile group is above the plane of the 1,3,4-thia-diazole ring and the other is below it, indicating syn and anti orientations. In the crystal, C-H⋯N hydrogen bonds link the molecules into ribbons along [010].
