摘要
Two new dicopper（II） complexes [Cu2L（OAc）2]（ClO4）·H2O （1） and [Cu2L（BPP）2]-（ClO4） （2） using an asymmetric dinucleating ligand HL and auxiliary ligands such as acetate （OAc） and bisphenyl phosphate （BPP） have been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. Complex 1 crystallizes as blue single crystals that belong to the triclinic crystal system and Pī space group, while complex 2 crystallizes in a monoclinic P21/c space group. Single-crystal X-ray diffraction analysis reveals that the two copper ions in complexes 1 and 2 reside within the adjacent ligand compartments and are bridged by the endogenous phenoxo-O from ligand L and the introduction of two desired exogenous carboxylates or phosphates in the bidentate μ-1,3-bridged mode. The coordination geometries of Cu（1） and Cu（2） are both distorted square pyramids.
