Tetra-μ-acetato-κ(8) O:O′-bis­{[2-(2-fur­yl)-1-(2-furylmeth­yl)-1H-benzimidazole-κN (3)]copper(II)}

The title complex, [Cu(2)(CH(3)COO)(4)(C(16)H(12)N(2)O(2))(2)], forms a dimer of the paddle-wheel type located on a crystallographic inversion centre. The two Cu(II) atoms [Cu⋯Cu = 2.7254 (11) Å] are bridged by four acetate anions. The geometry of the polyhedron around the metal centre can be descri...

Sumario:The title complex, [Cu(2)(CH(3)COO)(4)(C(16)H(12)N(2)O(2))(2)], forms a dimer of the paddle-wheel type located on a crystallographic inversion centre. The two Cu(II) 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 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.
