Dichloridobis(4-chloro-benz-yl)(4,4'-dimethyl-2,2'-bipyridine-κN,N')tin(IV).

ABSTRACT: The Sn(IV) atom in the title compound, [Sn(C(7)H(6)Cl)(2)Cl(2)(C(12)H(12)N(2))], is coordinated by the bidentate N-heterocycle mol-ecule, two chloro-benzyl anions and two Cl(-) anions in a distorted trans-C(2)SnCl(2)N(2) octa-hedral geometry [C-Sn-C = 178.4 (1)°]. In the mol-ecular structure, the two benzene rings are oriented at a dihedral angle of 39.62 (17)°.

Project description:In the structure of the title complex, [Cu(C(7)H(5)O(2))(OH)(C(12)H(12)N(2))(C(7)H(6)O(2))]·H(2)O, the Cu(II) ion is penta-coordinated in a tetra-gonal-pyramidal geometry with one O atom of a hydroxide group, one O atom of a benzoate anion and two N atoms of a 4,4'-dimethyl-2,2'-bipyridine ligand occupying the basal plane, and one O atom of a benzoic acid mol-ecule located at the apical site. The title complex was refined with a metal-coordinated OH group and a 'free' benzoic acid molecule, although it can be assumed that the proton is delocalized between the OH and the COOH group. The uncoordinated water mol-ecule is equally disordered over two positions. The structure displays O-H⋯O hydrogen bonding.
