摘要
合成了草酸根(ox)桥联[Cu(tmen)]2+单元(tmen为N,N,N′,N′-四甲基乙二胺)的一维多聚铜配合物.X-ray单晶衍射表明,该配合物由Cu(Ⅱ)和四个ox氧原子、tmen的两个氮原子配位形成畸变的八面体构型.Cu…Cu间距为0.560 95(34)nm和0.565 94(40)nm.水分子和草酸根间氢键可以使该配合物形成三维超分子结构.
A one-dimensional polymeric copper（Ⅱ） complex bridged by oxalato group （ox） and endcapped with N, N, N＇, N＇-tetramethylethylenediamine （tmen） was prepared and its crystal structure was determined by X-ray diffraction method. The copper （Ⅱ） atom has a distorted octahedral surrounding formed by four oxygen atoms, belonging to two bridging ox ligands, arid two nitrogen atoms of tmen. The [ Cu （tmen） ]^2＋ units are sequentially bridged by bis-bidentate ox ligands with Cu...Cu separations of 0. 560 95 （34） nm and 0. 565 94 （40） nm. Hydrogen bonds contribute to the formation of the threedimensional supramolecular structure.
