(Nitrato-κO,O')bis-(tryptanthrin-κN)silver(I).

ABSTRACT: In the crystal structure of the title compound, [Ag(NO(3))(C(15)H(8)N(2)O(2))(2)], tryptanthrin (indolo[2,1-b]quinazoline-6,12-dione) and silver nitrate form a 2:1 complex. The silver ion is surrounded by two tryptanthrin ligands, each coordinating through the N atoms, with Ag-N bond lengths of 2.247 (3) and 2.264 (3) Å, and an anionic nitrate ligand coordinating through two O atoms, with Ag-O bond lengths of 2.499 (3) and 2.591 (3) Å. The N-Ag-N plane and the O-Ag-O plane are roughly perpendicular, making a dihedral angle of 81.6 (2)°. In the crystal, C-H⋯O inter-actions between aromatic H atoms and keto and nitrate O atoms as well as π-π inter-actions [centroid-centroid distance = 3.706 (4) Å] give rise to a three-dimensional network.

Bis(imidazole-κN)bis-(nitrato-κO)zinc(II).

Project description:The title complex, [Zn(NO(3))(2)(C(3)H(4)N(2))(2)], contains a Zn(II) centre with a slightly distorted tetra-hedral coordination environment, involving two N atoms from imidazole ligands and two O atoms from nitrate anions. The imino NH groups participate in inter-molecular N-H⋯O hydrogen bonds.

Bis(μ(2)-3,5-diisopropyl-4H-1,2,4-triazole-κN:N)bis-[(nitrato-κO)silver(I)].

Project description:The neutral N-heterocycle in the title centrosymmetric dinuclear compound, [Ag(2)(NO(3))(2)(C(8)H(15)N(3))(2)], bridges two metal atoms through its imino N atoms. The N-Ag-N skeleton is bent [N-Ag-N = 127.2 (3)°]; as one of two O atoms of the nitrate anion is nearly coplanar with this N-Ag-N skeleton [Ag-O = 2.63 (1) Å], the coordination geometry around the Ag(I) atom is regarded as trigonal-planar. One of the two isopropyl groups is disordered over two positions in respect of the methyl groups in a 1:1 ratio. In the crystal structure, inter-molecular N-H⋯O hydrogen bonding is observed between the nitrate groups and triazole ligands.

Tetra-kis[bis-(pyridin-2-yl)amine-κN (2)](nitrato-κO)silver(I).

Project description:In the title complex, [Ag(NO3)(C10H9N3)4], the nitrate ligand is found to be disordered over two sets of positions, with occupancy factors of 0.473 (5) and 0.527 (5). The Ag(I) ion is located in a square-pyramidal coordination environment formed by four N atoms from four bis-(pyridin-2-yl)amine ligands and one O atom from a nitrate ligand. Weak inter-actions between the Ag(I) ions and the nitrate anions acting in a monodentate mode [Ag⋯O = 2.791 (13) and 2.816 (9) Å for the major component of the nitrate ligand, and 2.865 (8) and 2.837 (8) Å for the minor component] link the complex mol-ecules into a chain along [001]. N-H⋯O hydrogen bonds are observed.

Bis(2-amino-pyrimidine-κN)aqua-(nitrato-κO)(nitrato-κO,O')zinc(II).

Project description:The water-coordinated Zn atom in the title monoaqua zinc nitrate adduct of 2-amino-pyrimidine, [Zn(NO(3))(2)(C(4)H(5)N(3))(2)(H(2)O)], is bonded to a monodentate nitrate ion and is chelated by the other nitrate ion. The heterocyclic ligands coordinate through ring N-donor sites. The coordination geometry about the Zn(II) atom is a distorted octa-hedron. Intra-molecular N-H⋯O hydrogen bonds occur. In the crystal, adjacent adduct mol-ecules are linked by O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds into a layer motif parallel to (001).

Diaqua-bis-(nitrato-κO)bis-(pyridine-κN)manganese(II).

Project description:The structure of the title manganese complex, [Mn(NO3)2(C5H5N)2(H2O)2], consists of discrete monomeric entities with Mn(2+) ions located on centres of inversion. The metal cation is octahedrally coordinated by a trans-N2O4 donor set with the pyridine N atoms located in the apical positions. Discrete mol-ecules are linked by O-H⋯O hydrogen bonds into one-dimensional supra-molecular infinite chains along the b and c axes.

(Nitrato-κO)bis-[5-(pyridin-2-yl)pyrazine-2-carbonitrile-κN,N]silver(I).

Project description:In the mononuclear title complex, [Ag(NO(3))(C(10)H(6)N(4))(2)], two κ(2)N:N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, forming an N(4)O square-pyramidal coordination geometry with one nitrate anion bonding at the apical site. The two heterocyclic rings of the 5-(2-pyridin-2--yl)pyrazine-2-carbonitrile ligand are almost coplanar [dihedral angle = 5.63 (8)°], and the two chelating ligands are in an anti relationship. The mononuclear units are inter-connected along [010] through C-H⋯O(nitrate) and C-H⋯N(cyano) inter-actions, forming an infinite chain. The mononuclear units are stacked along the a axis and inter-connected via inter-molecular π-π stacking inter-actions between adjacent pyridine and pyrazine rings [centroid-centroid distances = 3.984 (2) and 3.595 (3) Å], thus forming a three-dimensional supra-molecular structure.

μ-2,3,5,6-Tetra-2-pyridylpyrazine-κN,N,N:κN,N,N-bis-[(methanol-κO)(nitrato-κO,O')(nitrato-κO)cadmium(II)].

Project description:The title complex, [Cd(2)(NO(3))(4)(C(24)H(16)N(6))(CH(4)O)(2)], displays a centrosymmetric dinuclear structure, in which the 2,3,5,6-tetra-2-pyridinylpyrazine (tppz) ligand links two Cd ions separated by 7.323 (4) Å. Each Cd(II) center is seven-coordinated by three N-atom donors of tppz in one plane, by two O atoms nearly normal to this plane, and by two O atoms 0.393 (3) and 0.488 (3) Å from that plane. The two Cd(II) ions are above and below the plane of the pyrazine ring of the tppz ligand, oriented with respect to the pyridine rings at dihedral angles of 38.01 (3) and 31.90 (3)°. The dihedral angle between the two pyridine rings is 41.11 (3)°. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules.

{3-[Bis(2-pyridyl-methyl-κN)amino-κN]propanol}bis-(nitrato-κO)copper(II).

Project description:In the title compound, [Cu(NO(3))(2)(C(15)H(19)N(3)O)], the Cu(II) ion is coordinated by the N atoms of the tetra-dentate 3-[bis-(2-pyridyl-meth-yl)amino]-propanol ligand and two O atoms from two monodentate nitrate anions, resulting in a distorted square-pyramidal environment. An inter-molecular O-H⋯O hydrogen-bonding inter-action between the free hy-droxy group of the ligand and a nitrate O atom of an adjacent complex unit, gives a chain structure which extends across the (101) planes.

μ-Adipato-κO:O-bis-{[2,6-bis-(1H-benzimidazol-2-yl-κN)pyridine-κN](nitrato-κO)lead(II)}.

Project description:The dinuclear title compound, [Pb(2)(C(6)H(8)O(4))(NO(3))(2)(C(19)H(13)N(5))(2)], lies with the mid-point of the butyl chain of the bridging adipate unit on a center of inversion. The Pb(II) ion is covalently bonded to the nitrate anion and is bonded to a carboxyl-ate group of the adipate unit by another covalent bond. The N-heterocycle functions in a chelating tridentate mode. The metal atom exists in a Ψ-octa-hedral coordination environment. When weaker Pb⋯O inter-actions are also considered, the geometry is a Ψ-tricapped trigonal prism in which the lone-pair electrons occupy one face of the trigonal prism. Adjacent mol-ecules are linked into a layer structure by N-H⋯O hydrogen bonds.

Bis(cyanamide-κN)[4-(1H-imidazol-1-yl)phenol-κN]bis-(nitrato-κO)copper(II).

Project description:A pair of linear cyanamide (NCNH(2)) ligands, two monodentate 4-(1H-imidazol-1-yl)phenol (L) ligands and two nitrate anions link the Cu(II) atom into a mononuclear unit, [Cu(NO(3))(2)(C(9)H(8)N(2)O)(2)(NCNH(2))(2)]. The coordination polyhedron of the Cu atom is an elongated octa-hedron distorted by Jahn-Teller effects. Inter-molecular O-H⋯O, O-H⋯N, N-H⋯O and N-H⋯N hydrogen-bonding inter-actions link these units into a three-dimensional supra-molecular architecture.
