摘要
A supramolecular Cu(II) complex [CuL(H2O)] with an asymmetric salen-type bisoxime ligand (H2L = 4-nitro-6'-methoxy-2,2'-[ethylenediyldioxybis(nitrilomethylidyne)]diphenol) has been synthesized and characterized by elemental analysis, IR and UV/Vis spectroscopy, TG-DTA analysis, and molar conductance measurements. The crystal structure of the Cu(II) complex has been determined by single-crystal X-ray diffraction. The Cu(11) atom is penta-coodinated by N2O2 donor atoms from the asymmetic salen-type bisoxime L2- unit and one oxygen atom from the coordinated water molecule, resulting in an almost regular square-pyramidal geometry. With the help of intermolecular O-H center dot center dot center dot O, C-H center dot center dot center dot O hydrogen bonding and pi center dot center dot center dot pi stacking interactions, a self-assembled 3D supramolecular structure is formed.
