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 tetra-gonal-pyramidal derived from the calculation of the value τ = 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.
标题配合物[Cu₂(CH₃COO)₄(C₁₆H₁₂N₂O₂)₂]形成了一个位于晶体学反演中心的桨轮型二聚体。两个Cu(II)原子[Cu⋯Cu = 2.7254 (11) Å]由四个醋酸根阴离子桥连。根据τ = 0.0018的计算结果，金属中心周围多面体的几何形状可描述为四方锥型。四方锥型铜配位多面体的顶端位置由2-(2-呋喃基)-1-(2-呋喃甲基)-1H-苯并咪唑配体的N原子占据。在晶体结构中，分子通过平行于[010]的分子间C-H⋯O氢键连接成链。两个呋喃环在两个位置上无序分布，比例分别为0.55:0.45和0.69:0.31。
