摘　　要：在水热条件下合成了一例CuⅠ-GdⅢ异金属二维结构的配位聚合物[GdⅢCuⅠ2(Hbpdc)4]·Cl·8H2O(1)(H2bpdc=2,2′-联吡啶-5,5′-二羧酸),并对其结构进行了表征.X射线单晶衍射结果表明1属于单斜晶系,C2/c空间群.化合物1最显著的结构特征是Gd3+阳离子与[Cu(Hbpdc)2]-阴离子交替连接形成二维网状结构,结晶水分子有规律地填充在二维层的间隙中.A CuⅠ-GdⅢheterometallic coordination polymer[GdⅢCuⅠ2（Hbpdc）4]·Cl·8H2O（H2bpdc= 2,2′-bipyridyl-5,5′-dicarboxylic acid）（1）with a two-dimensional extended architecture has been hydrothermally obtained and structurally characterized.Single-crystal X-ray diffraction indicates that 1 belongs to the monoclinic space group C2/c.The most prominent structural characteristic of 1is that Gd3＋cations and[Cu（Hbpdc）2]- anions are distributed alternatively to form an aesthetic two-dimensional network structure with lattice water molecules stuffing in the neighboring interlayer voids regularly.
