Bis(2-amino-4-methyl-1,3-thia-zole-?N)dichloridocadmium(II).

ABSTRACT: In the title compound, [CdCl(2)(C(4)H(6)N(2)S)(2)], the Cd(II) atom is coordinated by two chlorido ligands and two N atoms of the 2-amino-5-methyl-1,3-thia-zole (amtz) ligands in a slightly distorted tetra-hedral coordination geometry. Intra- and inter-molecular N-H?Cl hydrogen bonding stabilizes the crystal structure. A weak S?Cl inter-action [3.533?(2)?Å] is observed between neighboring mol-ecules.

Tetra-kis(2-amino-thia-zole-?N)dichloridocadmium(II).

Project description:In the title complex, [CdCl(2)(C(3)H(4)N(2)S)(4)],the Cd(II) atom has an trans-Cl(2)N(4) octa-hedral coordination geometry defined by four N atoms derived from the four 2-amino-thia-zole ligands and two Cl atoms. The amino groups participate in intra- and inter-molecular N-H?N and N-H?Cl hydrogen bonding that stabilizes both the mol-ecular and crystal structures.

catena-Poly[[trans-bis-(1,3-benzo-thia-zole-?N)manganese(II)]-di-?-chlorido].

Project description:In the title coordination polymer, [MnCl2(C7H5NS)2] n , the Mn(II) ion is located on the inter-section of a twofold rotation axis and a mirror plane and adopts an octa-hedral coordination geometry defined by two mutually trans N atoms from benzo-thia-zole ligands which occupy the axial positions, and four Cl atoms which form the equatorial sites. The Mn(II) ions are connected by two bridging Cl atoms, forming chains parallel to the c axis. The crystal packing can be descibed as alternating layers parallel to (001) featuring ?-? stacking inter-actions with a centroid-centroid distance of 3.6029?(15)?Å.

Bis(2-amino-1,3-thia-zole-?N)diazido-zinc.

Project description:In the title complex, [Zn(N(3))(2)(C(3)H(4)N(2)S)(2)], the Zn(II) atom is tetra-hedrally coordinated by two terminal azide ligands and by the ring N atoms of two different 2-amino-thia-zole ligands. Intra-molecular N-H?N hydrogen bonds between the amino groups of both 2-amino-thia-zole ligands and the N atom of one of the azide ligands ensure that the heterocyclic rings are oriented in the same direction. Inter-molecular N-H?N hydrogen bonds link the mol-ecules into zigzag sheets in the ac plane.

Crystal structure of (1,3-thia-zole-2-carboxyl-ato-κN)(1,3-thia-zole-2-carb-oxy-lic acid-κN)silver(I).

Project description:The linear two-coordinate silver (I) complex [Ag(C4H2NO2S)(C4H3NO2S)] or [Ag(2-Htza)(2-tza)] is reported (2-Htza = 1,3-thia-zole-2-carb-oxy-lic acid). The AgI ion is coordinated by two heterocyclic N atoms from two ligands in a linear configuration, forming a discrete coordination complex. There is an O-H⋯O hydrogen bond between 2-tza- and 2tzaH of adjacent complexes. The hydrogen atom is shared between the two oxygen atoms. This inter-action produces a hydrogen-bonded tape parallel to the [110] direction, which is augmented through inter-molecular C-H⋯O hydrogen-bonding inter-actions between the bound thia-zole groups. There is a further rather long Ag⋯O inter-action [2.8401 (13) Å, compared with a mean of 2.54 (11) Å for 23 structures in the CSD] that assembles these tapes into columns, between which there are C-H⋯π inter-actions, leading to the formation of a three-dimensional supra-molecular architecture.

catena-Poly[bis(1,3-benzo-thia-zol-3-ium) [[di-chlorido-anti-monate(III)]-di-?-chlorido-?-oxido-[chlorido-anti-monate(III)]-?-chlorido]].

Project description:The title compound, {(C7H6NS)2[Sb2Cl6O]} n , contains two benzo-thia-zolidium cations and one tri-?-chlorido-tri-chlorido-?-oxido-di-anti-monate(III) anion. The structure of the inorganic cation may be described as as being built up from two polyhedra, i.e. a square-pyramidal SbCl4O and a distorted octa-hedral SbOCl5 unit, sharing a common face (comprising the O atom and two Cl atoms). The two benzo-thia-zole cations are quasi-planar and subtend a dihedral angle of 19.93?(5)°. The crystal packing can be described by alternating (100) layers and [001] chains of the organic cations and inorganic anions connected through an extensive three-dimensional network of N-H?Cl, C-H?O and C-H?Cl hydrogen bonds. This is consolidated by slipped ?-? stacking, with centroid-to-centroid distances between the benzo-thia-zole rings of 3.7111?(18)-3.8452?(16)?Å. These inter-actions link the mol-ecules within the layers and also link the layers together and reinforce the cohesion of the ionic structure.

Bis{1,2-bis-[2-(1H-imidazol-1-yl)eth-oxy]ethane-?N,N}dichloridocadmium(II) monohydrate.

Project description:The asymmetric unit of the title compound, [CdCl(2)(C(12)H(18)N(4)O(2))(2)]·H(2)O, contains one water mol-ecule and two halves of a [CdCl(2)(BIEE)(2)] complex mol-ecule {BIEE is 1,2-bis-[2-(1H-imidazol-1-yl)eth-oxy]ethane}, with the Cd(II) atoms lying on inversion centres. Each metal atom displays an elongated octa-hedral coordination geometry provided by two trans-arranged chloride anions and four N atoms from two BIEE ligands. Weak O-H?Cl hydrogen-bond inter-actions contribute to the stability of the crystal packing.

The crystal structure is stabilized by inter-molecular C-H?Cl and C-H?O hydrogen bonds.

Project description:In the title compound, [CdCl(2)(C(5)H(7)N(3)O)(2)], the Cd(II) atom is six-coordinated by two heterocyclic N atoms [Cd-N = 2.261?(2) and 2.286?(2)?Å] and two O atoms [Cd-O = 2.624?(2) and 2.692?(2)?Å] from two bidentate chelate 2-amino-6-methyl-pyrimidin-4(1H)-one ligands and two chloride ions [Cd-Cl = 2.4674?(6) and 2.4893?(7)?Å]. The crystal packing is characterized by an open-framework architecture with the crystal packing stabilized by inter-molecular N-H?Cl and N-H?O hydrogen bonds.

[(E)-But-2-enoato-?O]chlorido(2,2'-diamino-4,4'-bi-1,3-thia-zole-?N,N)zinc(II) monohydrate.

Project description:In the title compound, [Zn(C(4)H(5)O(2))Cl(C(6)H(6)N(4)S(2))]·H(2)O, the Zn(II) cation is coordinated by a bidentate diamino-bithia-zole (DABT) ligand, a but-2-enoate anion and a Cl(-) anion in a distorted tetra-hedral geometry. Within the DABT ligand, the two thia-zole rings are twisted to each other at a dihedral angle of 4.38?(10)°. An intra-molecular N-H?O inter-action occurs. The centroid-centroid distance of 3.6650?(17)?Å and partially overlapped arrangement between nearly parallel thia-zole rings of adjacent complexes indicate the existence of ?-? stacking in the crystal structure. Extensive O-H?Cl, O-H?O, N-H?Cl and N-H?O hydrogen bonding helps to stabilize the crystal structure.

Bis(2-amino-4-phenyl-1,3-thia-zol-3-ium) tetra-chlorido-palladate(II).

Project description:The title compound, (C9H9N2S)2[PdCl4], consists of two monoprotonated 2-amino-4-phenyl-1,3-thia-zole molecules and one tetra-chlorido-palladate anion. The organic molecules exhibit a dihedral angle between the main rings planes of 31.82?(9)°. In the anion, the Pd(II) atom is located on a crystallographic centre of symmetry with a square-planar geometry. In the crystal, the anions and cations are connected through bifurcated N-H?Cl hydrogen bonds, and these inter-actions lead to hydrogen-bonded tapes of cations and anions along [100].
