Catena-Poly[(dichloridocadmium)-di-?-chlorido-[bis-(morpholinium-?O)cadmium]-di-?-chlorido].

ABSTRACT: In the title compound, [Cd(2)Cl(6)(C(4)H(10)NO)(2)](n), the coordination geometry of each Cd(II) ion is distorted octa-hedral, but with quite different coordination environments. One Cd(II) atom is coordinated by four Cl atoms and two O atoms from two morpholinium ligands, while the other is coordinated by six Cl atoms. Adjacent Cd(II) atoms are inter-connected alternately by paired chloride bridges, generating a chain parallel to the a axis. Inter-chain N-H?Cl inter-actions form a two-dimensional network.

Project description:The title complex, [CdCl(2)(C(9)H(12)N(4))](n), is characterized by the formation of a zigzag chain structure parallel to [001]. In the chain, the Cd(2+) cation is coordinated by four bridging Cl(-) ligands in equatorial positions and two N atoms from symmetry-related and likewise bridging 1,3-bis-(imidazol-1-yl)propane ligands in axial positions, forming a distorted CdCl(4)N(2) octa-hedron.

catena-Poly[[bis[quinazolin-4(3H)-one-?N]cadmium(II)]-di-?-chlorido].

Project description:The asymmetric unit of the title compound, [CdCl(2)(C(8)H(6)N(2)O)(2)](n), consists of one mol-ecule of the 3H-quinazolin-4-one ligand, one Cd(2+) cation, which is located on a twofold axis, and one chlorido ligand in a general position. The latter bridges metal cations, forming a one-dimensional polymer along the b axis. The Cd?Cd distance along the chain is 3.7309?(7)?Å. The octa-hedral coordination around the metal is completed by two ligands in a trans axial geometry which coordinate through the N atom in 1 position. Moderately strong classical N-H?O hydrogen bonds around crystallographic inversion centers cross-link adjacent polymeric chains.

Project description:The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely distorted fivefold coordination by four Cl atoms and one N atom from a 1-ethyl-1H-imidazole ligand. Adjacent Cd(II) cations are inter-connected alternately by pairs of chloride bridges, generating an infinite step-like chain along the a axis. One ethyl group of the 1-ethyl-1H-imidazole ligand is disordered over two sets of sites with a 0.668?(13):0.332?(13) site-occupancy ratio.

Project description:The asymmetric unit of the title compound, [CdCl(2)(C(12)H(12)N(2))](n), contains one half-mol-ecule; a twofold rotation axis passes through the Cd atom. The Cd(II) atom is six-coordinated in a distorted octa-hedral configuration by two N atoms from 2,2'-bipyridine-5,5'-dimethyl and four bridging Cl atoms. The bridging function of the chloro atoms leads to a one-dimensional chain structure. There is a ?-? contact between the pyridine rings [centroid-centroid distance = 3.9807?(9)?Å].

Project description:The crystal structure of the title complex, {(C(2)H(8)N)[CuCl(2)(N(3))]}(n), exhibits inorganic chains consisting of Cu(II) cations as well azide and chloride anions.

catena-Poly[bis-(4-amino-pyridinium) [[diaqua-manganese(II)]-di-?-chlorido] dichloride].

Project description:Single crystals of the title organic-inorganic hybrid, {(C(5)H(7)N(2))(2)[MnCl(2)(H(2)O)(2)]Cl(2)}(n), were synthesized from an ethanol solution containing manganese(II) chloride tetra-hydrate and 4-amino-pyridine under acidic conditions. The asymmetric unit contains a disordered organic cation (occupancies in the ratio 0.72:0.28), a chloride anion and an MnCl(H(2)O) moiety with the Mn(II) atom located on an inversion center. The structure is built up of infinite chains of edge-sharing [MnCl(4)(H(2)O)(2)] octa-hedra developing parallel to the a axis which are separated by the 4-amino-pyridinium ions and discrete chloride ions. The organic cations occupy the empty space around each inorganic chain. Structural cohesion is organized through N-H?Cl and O-H?Cl hydrogen bonds, which build up a three-dimensional network.
