一种新的氢键三维网络配位化合物[CuL_2](H_2L)(C_5H_6)_2的合成与表征(英文)

Synthesis and Characterization of a New Hydrogen-bonded Three-dimensional Network General Complex (H_2L)(C_5H_6)_2

合成一种以草盐酸盐为配体的四配位CuII新颖的三聚配合物[CuL2](H2L)(C5H6)2(H2L=草酸),并通过元素分析和X-ray衍射分析确定其结构.该配合物的晶体结构显示CuII中心有CuO4平行四边形平面环境,CuII位于平行四边形的中心.通过分子内的C—H…O氢键相互作用2个吡啶鎓桥联相临的2个Cu(L)22-层形成3-D网络.

A four-coordinated Cu^Ⅱ complex with a novel trimers of oxalate ligand （ [ Cu （ L） 2 ] { H2 L） （ C5 H6 ） 2, where H2L = oxalic acid ） has been synthesized and characterized by elemental analyses and X-ray diffraction techniques. The crystal structure of this complex reveals that the Cu^Ⅱ center has a CuO4 parallelogram plane environment and CuII locates in the center of the parallelogram. Furthermore, two Cu{ L} 2^2 layers adjacent to pyridine bridge form 3-D networks through intermolecular C-H……O hydrogen-bonded interactions.
