Cu(1) and Cu(1A) are both five-coordinated by four oxygen atoms from four μ2-CH3CO2- and one nitrogen atom from bridging ligand, forming a distorted square-pyramidal coordination configuration. Cu(1) and Cu(1A) are linked via four μ2-bridged CH3CO2- anions to form a paddle-wheel structural unit, which furthermore self-assemble into 1D chain via bridging ligands. CCDC: 603429.展开更多
