摘要 利用水热技术合成了单核和双核酒石酸铜的配合物[Cu(C6H6N4)(C4H4O6)(H2O)].H2O和[Cu2(C4H4O6)2-(H2O)2].4H2O,通过X-射线单晶衍射、热重分析、IR和元素分析进行了表征。结果表明,在第一个配合物中R,R-酒石酸和联咪唑均以双齿配位与铜形成单核配合物,分子间通过氢键构筑了无限的三维网状结构。而在第二个配合物中2个S,S-酒石酸分子同时与2个铜离子配位形成环合结构,结构单元间通过"手拉手"相联形成二维的无限层状结构,层间通过氢键相联构成三维无限的网状结构。单核配合物的热稳定性高于双核配合物。 Mono-and dinuclear copper（Ⅱ） tartrate complexes,[Cu（C6H6N4）（C4H4O6）（H2O）]·H2O and [Cu2-（C4H4O6）2（H2O）2]·4H2O were synthesized under hydrothermal conditions and were characterized by X-ray single crystal diffraction,TG,IR and elemental analysis.The results showed that R,R-tartaric acid and 2,2-H2biim were coordinated with a copper atom as bidentate ligands respectively in [Cu（C6H6N4）（C4H4O6）（H2O）]·H2O.An infinite 3D network was formed through hydrogen bonding.[Cu2（C4H4O6）2-（H2O）2]·4H2O,a closodicopper complex,was formed through two S,S-tartaric acid molecules bridging two Cu（Ⅱ） cations.Thereby each structure unit was linked by ＂hand in hand＂ to construct a 2D infinite layer structure.In addition,the 2D networks were further connected through hydrogen bonds to construct a 3D framework.In comparison with [Cu2-（C4H4O6）2（H2O）2]·4H2O,the hydrothermal stability of [Cu（C6H6N4）（C4H4O6）（H2O）]·H2O was better than that of [Cu2（C4H4O6）2（H2O）2]·4H2O.
