Catena-Poly[2-methyl-1H-imidazol-3-ium [(aqua-chloridocadmate)-di-μ-chlorido]].

ABSTRACT: The asymmetric unit of the title compound, {(C(4)H(7)N(2))[CdCl(3)(H(2)O)]}(n), contains one 1-methyl-1H-imidazol-3-ium cation, one Cd(II) atom, three Cl atoms and one water mol-ecule. Adjacent Cd ions are inter-connected alternately by paired Cl(-) bridges to generate an infinite one-dimensional coordination chain along the b axis. In the chain, the crystallographically unique Cd(II) atom, with a distorted octa-hedral geometry, is coordinated by five Cl(-) ions and one water mol-ecule. Intra-chain O-H⋯Cl hydrogen bonding and N-H⋯Cl hydrogen bonding between the cations and the anionic chains consolidate the crystal packing.

catena-Poly[[trimeth-yl(4-sulfanylphen-yl)aza-nium] [(chloridocadmate)-di-μ-chlorido]].

Project description:The title compound, {(C(9)H(14)NS)[CdCl(3)]}(n), consists of a linear [CdCl(3)](n) (n) (-) polyanion and a trimeth-yl(4-sulfanylphen-yl)aza-nium cation. The Cd(II) atom is penta-coordinated by four μ(2)-Cl atoms and one terminal Cl atom in a trigonal-bipyramidal geometry. The trigonal-bipyramidal units are linked by two opposite shared faces, giving rise to infinite [CdCl(3)](n) chains parallel to the a axis. The cations surround the chain and are linked to them by S-H⋯Cl and C-H⋯Cl hydrogen bonds, forming a three-dimensional network.

Project description:In the polymeric title complex, [CdCl(2)(C(12)H(13)N(5))](n), the Cd(II) atom is five-coordinated by two N atoms from two bridging 1-[(2-ethyl-1H-imidazol-1-yl)meth-yl]-1H-benzotriazole (bmei) ligands, two bridging Cl atoms and one terminal Cl atom in a distorted trigonal-bipyramidal geometry. The Cd(II) atoms are connected alternately by the Cl atoms and bmei ligands, leading to a zigzag chain extending parallel to [011]. π-π inter-actions, with a centroid-centroid distance of 3.3016 (3) Å, help to stabilize the crystal packing.

catena-Poly[[aqua-glycolatocopper(II)]-μ-chlorido].

Project description:In the crystal structure of the title compound, [Cu(C(2)H(3)O(3))Cl(H(2)O)](n), the Cu(II) ion is five-coordinate in a distorted square-pyramidal geometry. Two O atoms from a chelating glycolate anion, an O atom from a coordinated water mol-ecule and a chloride anion comprise the basal plane. A chloride ion from a neighbouring unit occupies the apical position and these Cu-Cl-Cu bridges link the aqua-glycolatocopper(II) units into one-dimensional chains along the [001] direction. These chains are connected by O-H⋯O and O-H⋯Cl hydrogen bonds, forming an infinite three-dimensional polymeric network.

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

Project description:The title compound, {(C7H6NS)2[Sb2Cl6O]} n , contains two benzo-thia-zolidium cations and one tri-μ-chlorido-tri-chlorido-μ-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 π-π 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.

catena-Poly[copper(I)-bis-[μ-3-(1H-imidazol-2-yl)pyridine]-copper(I)-di-μ-iodido].

Project description:The title polymeric compound, [Cu(2)I(2)(C(8)H(7)N(3))(2)](n) [C(8)H(7)N(3) = 3-(1H-imidazol-2-yl)pyridine (HIPy), where HIPy comes from the in situ deca-rboxylation of 2-(pyridin-3-yl)-1H-imidazole-4,5-dicarb-oxy-lic acid (H(3)PyIDC)], was obtained under solvo-thermal conditions. Each Cu(I) cation is in a distorted tetra-hedral coordination environment defined by two iodide anions and two nitro-gen atoms from two individual HIPy ligands. Two Cu(I) atoms are connected by two HIPy ligands to form a dimer and these dimers are further bridged through the iodide atoms, leading to a chain structure extending parallel to [100]. Moreover, inter-molecular N-H⋯I hydrogen bonds and weak π-π stacking inter-actions [centroid⋯centroid distances of 3.809 (4) Å, an inter-planar separation of 3.345 (3) Å and a ring slippage of 1.822 Å] between pyridyl rings link the chains into a two-dimensional supra-molecular network in the ac plane.

In the crystal, adjacent mol-ecules are linked through N-H⋯N and N-H⋯O hydrogen bonds into a three-dimensional network.

In the dianion, the planar 5-amino-4-amino-carbonyl-1H-imidazol-3-ium ligand occupies an equatorial site and is inclined at an angle of 75.7 (2)° to the Bi(2)(μ-C1)(2) plane. The salt forms a three-dimensional network arising from hydrogen bonds between cations, anions and water mol-ecules.
