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[GdⅢ CuⅠ2（Hbpdc）4]・Cl・8H2 O （1）（H2 bpdc ＝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‐GdⅢ heterometallic coordination polymer [GdⅢ Cu2Ⅰ (Hbpdc)4 ]・ Cl・8H2 O (H2 bpdc = 2 ,2′‐bipyridyl‐5 ,5′‐dicarboxylic acid) (1) with a two‐dimensional extended archi‐tecture 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 1 is that Gd3+ cations and [Cu(Hbpdc)2 ]- anions are distributed al‐ternatively to form an aesthetic two‐dimensional network structure with lattice water molecules stuffing in the neighboring interlayer voids regularly .
