Tetra - Acetato-8 O:O′-bis-{[2-(2-fur-yl)-1-(2-furylmeth- yl)-1H-benzimidazole-N 3]copper(II)}

Abstract

The title complex, [Cu2 (CH3COO)4 (C 16H12N2O2)2], forms a dimer of the paddle-wheel type located on a crystallographic inversion centre. The two CuII atoms [Cu⋯Cu = 2.7254 (11) Å] are bridged by four acetate anions. The geometry of the polyhedron around the metal centre can be described as tetra-gonal-pyramidal derived from the calculation of the value = 0.0018. The apical positions of the tetra-gonal-pyramidal copper coordination polyhedra are occupied by the N atoms of 2-(2-fur-yl)-1-(2- furylmeth-yl)-1H-benzimidazole ligands. In the crystal structure, mol-ecules are linked into a chain by inter-molecular C - H⋯O hydrogen bonds parallel to [010]. Two furan rings are disordered over two positions in ratios of 0.55:0.45 and 0.69:0.31. © 2009 Wang et al.
