Project description:In the title coordination polymer, [CdI(2)(C(12)H(12)N(2))](n), the Cd(2+) ion lies on a twofold rotation axis: it is six-coordinated in a distorted cis-CdN(2)I(4) octa-hedral geometry by two N atoms from a chelating 5,5'-dimethyl-2,2'-bipyridine ligands and four bridging iodide anions. The bridging function of the iodide ions leads to a chain structure propagating in [001].

Project description:In the crystal of the title polymeric compound, [CdBr2(C12H12N2)] n , the Cd(II) cation is located on a twofold rotation axis and is six-coordinated in a distorted octa-hedral geometry formed by two N atoms from the 4,4'-dimethyl-2,2'-bipyridine ligand and by four bridging Br(-) anions. The bridging function of the Br(-) anions leads to a polymeric chain running along the c axis. Weak C-H?? inter-actions observed between adjacent chains are effective in the stabilization of the three-dimensional packing.

catena-Poly[1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium [lead(II)-tri-μ-iodido-lead(II)-tri-μ-iodido]].

Project description:The title compound, {(C(14)H(18)N(2))[Pb(2)I(6)]}(n), consists of discrete 1,1'-dimethyl-4,4'-(ethane-1,2-di-yl)dipyridinium cations and one-dimensional [Pb(2)I(6)](n) anions. The organic cation has an inversion center at the mid-point of the ethane C-C bond. In the anion, the Pb(II) atom is coordinated by six I atoms in a distorted octa-hedral geometry. The I atoms bridge the Pb(II) atoms into a polymeric chain running along [001]. These inorganic chains are separated by the isolated organic cations.

catena-Poly[[?-bromido-(?-hydroxydi-2-pyridylmethano-lato-?N,O:O,N')dicopper(II)(Cu-Cu)]-di-?-bromido].

Project description:The title complex, [Cu(2)Br(3)(C(11)H(9)N(2)O(2))](n), was one of three isolated by slow evaporation of an acetonitrile reaction mixture of CuBr(2) with di-2-pyridyl ketone (1:1 molar ratio). The title complex contains a 2:1 metal-to-ligand ratio of copper(II) with the hydrated form of the ligand, di-2-pyridylmethane-diol. The two copper centers are bridged by a bromide ion and the alk-oxy O atom, and the Cu-Cu distance is 2.9801?(5)?Å. The dimeric units are further linked by bromide ions, leading to a two-dimensional extended bridged structure. O-H?O hydrogen bonds are present in the crystal structure.

Project description:In the centrosymmetric tetra-nuclear title compound, [Cu(4)I(4)(C(10)H(8)N(2)S(2))(2)], there are two different Cu(I) atoms with tetra-hedral coordination geometries. One is chelated by a pyridine N atom and an S-donor from one di-2-pyridyl disulfide ligand and coordinated by two I atoms, while the second Cu(I) atom is coordinated by a pyridine-N and three I atoms. Iodine bridges between the Cu(I) atoms form a tetra-nuclear structure.

catena-Poly[[[diaqua-copper(II)]-bis-(?(2)-di-4-pyridyl disulfide-?N:N')] bis-(hydrogen phthalate) monohydrate].

Project description:The asymmetric unit of the title compound, {[Cu(C(10)H(8)N(2)S(2))(2)(H(2)O)(2)](C(8)H(5)O(4))(2)·H(2)O}(n), contains one Cu(II) ion, two bridging di-4-pyridyl disulfide (4-DPDS) ligands of the same chirality, two coordinating water mol-ecules, two hydrogen phthalate anions and one uncoordinated water mol-ecule. The polymeric structure consists of two types of polymeric chains, each composed from repeated chiral rhomboids. The Cu(II) ions adopt a distorted octa-hedral coordination geometry and are coordinated by four pyridine N atoms and two water O atoms. The coordinated water mol-ecules and hydrogen phthalate anions are located between the repeated rhomboidal chains, and form hydrogen bonds with the coordinated water mol-ecules.

catena-Poly[[bis-(μ(2)-1,4,7,10,13,16-hexa-oxacyclo-octa-deca-ne)dipotassium]-μ(2)-iodido-(iodidocadmium)-di-μ(2)-iodido-(iodidocadmium)-μ(2)-iodido].

Project description:The reaction of CdCl(2), 18-crown-6 and KI in water yields the title coordination polymer, [{K(C(12)H(24)O(6))}(2)Cd(2)I(6)](n). The potassium ion lies approximately in the plane of the crown ether, coordinated by all six crown ether O atoms and also by an iodide anion bound to a cadmium atom. A C atom of the crown ether is disordered over two positions with site occupancies of 0.77 (2) and 0.23 (2). Two K(18-crown-6)(+) units are linked by inversion symmetry, forming a [bis-(μ(2)-18-crown-6)dipottasium] system with approximately square-planar K(2)O(2) units. Inversion symmetry also generates the Cd(2)I(6) fragment and the polymeric system is extended along the c axis by the formation of K-I-Cd bridges.
