摘要
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) A] 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.
