Catena-Poly[[(4,4'-dimethyl-2,2'-bipyridine-?(2) N,N')cadmium]-di-?-bromido].

ABSTRACT: 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.

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].

catena-Poly[[(2,2'-bipyridine)-manganese(II)]-?(3)-4,4'-sulfonyl-dibenzoato].

Project description:In the title compound, [Mn(C(14)H(8)O(6)S)(C(10)H(8)N(2))](n), the Mn(II) ion is coordinated by four O atoms from three 4,4'-sulfonyl-dibenzoate (sdba) ligands and two N atoms from one 2,2'-bipyridine (2,2'-bipy) ligand in a distorted octa-hedral geometry. The manganese atoms are alternately bridged either by two sdba ligands, with an Mn?Mn separation of 12.284?(1)?Å, or by two carboxyl-ate groups from two sdba ligands, with an Mn?Mn separation of 4.064?(1)?Å, thus producing polymeric chains propagated in [101]. Weak inter-molecular C-H?O hydrogen bonds and ?-? inter-actions [centroid-centroid distance of 3.730?(3)?Å between the aromatic rings of neighbouring polymeric chains] further stabilize the crystal packing.
