摘要：
A new ligand of N-benzyl-N’-(2-pyridyl)urea L and its self-assembly product with CuCl2,[Cu(II)LCl2]∞ 1,have been synthesized and structurally characterized by IR,1H NMR and single-crystal X-ray diffraction analysis. In the structure of L,the urea groups adopt Z,E conformation to form dimers through intermolecular hydrogen bonds; while in complex 1,it assumes Z,Z conformation to fit for the coordination sphere of the Cu(II) ions. The coordinated units are connected through intermolecular N-H···Cl hydrogen bonds to form an extended 2D framework. Finally,a 3D structure is obtained via π-π stacking interactions between pyridyl rings.
