The dihedral angle between the benzene rings of the ligand is 51.0?(1)° and the dihedral angles between the benzene rings and their attached imidazole rings are 18.7?(2) and 45.9?(1)°. The bridging ligand leads to [10-1] polymeric chains in the crystal and the disordered water mol-ecule (occupancy 0.25) forms O-H?Cl hydrogen bonds.

Project description:The title one-dimensional coordination polymer, {[Zn(NCS)(2)(C(24)H(20)N(6))(2)]·0.28H(2)O}(n), was obtained by the reaction of Zn(OAc)(2)·2H(2)O, KSCN and 1,2-bis-{[2-(2-pyrid-yl)-1H-imid-azol-1-yl]meth-yl}benzene (hereafter L). The Zn(II) ion shows a distorted octa-hedral coordination geometry and is coordin-ated by two N atoms from two SCN(-) anions and four N atoms from two organic ligands. The L ligands act as bridging bis-chelating ligands with cis coordination modes at the Zn(II) ion. One-dimensional coordination polymers are arranged into layers by ?-? stacking inter-actions between the imidazole rings of adjacent chains, with an inter-planar distance of 3.46?(1)?Å and centroid-centroid distances of 3.8775?(16)?Å. One of the thio-cyanate ligands is disordered over two positions with an occupancy factor of 0.564?(3) for the major component. The partially occupied water mol-ecule forms an O-H?S hydrogen bond with the disordered thio-cyanate group.

Project description:In the title compound, [Co(NO(3))(2)(C(20)H(18)N(4))](n), the Co(II) atom lies on a crystallographic twofold axis and the coordination geometry can be considered as a slightly distorted tetra-hedron defined by two O atoms from two nitrate groups and two N atoms from two ligand mol-ecules. A distorted octa-hedron may be assumed when two of the symmetry-related nitrate O atoms with Co-O distances of 2.3449?(19)?Å are added to the coordination environment. Another twofold axis, passing through the middle of the biphenyl bonds, is observed in the crystal structure. A chain is built up by the ligands linking the Co(II) ions along [101].

The dihedral angle between the benzimidazole ring system and the adjacent benzene (B) ring is 51.12?(11)° and the dihedral angle between the B ring and the central ring is 19.45?(13)°.
