Abstract:

The title complex, [Cu2(CH3COO)4(C16H12N2O2)2], forms a dimer of the paddle-wheel type located on a crystallographic inversion centre. The two CuII atoms [Cu...Cu = 2.7254 (11) ] are bridged by four acetate anions. The geometry of the polyhedron around the metal centre can be described as tetragonal-pyramidal derived from the calculation of the value τ = 0.0018. The apical positions of the tetragonal-pyramidal copper coordination polyhedra are occupied by the N atoms of 2-(2-furyl)-1-(2-furylmethyl)-1H-benzimidazole ligands. In the crystal structure, molecules are linked into a chain by intermolecular 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.
