摘　　要：水热法合成了两个新颖的有机-无机杂合化合物{[Cu(o-phen)(H2O)]3[Mo5P2O23]}?4.5H2O(1)和{[Cu(o-phen)-(H2O)]2[Mo5Se2O21]}(2)(o-phen=1,10-phenanthroline).通过红外光谱和单晶X射线衍射分析确定了它们的结构.结构分析表明两个分子结构中的相邻[Mo5P2O23]6-或[Mo5Se2O21]4-阴离子均由两个桥式的[Cu(o-phen)(H2O)]单元连接成分别为风车状和双侧桥联状一维聚合链,化合物1的双金属链又通过若干链间氢键形成层状堆积结构.讨论了钼杂多酸阴离子和第二种金属-配体亚单元阳离子之间的相互匹配关系.Two novel organic-inorganic hybrid compounds {[Cu（o-phen）（H2O）]3[Mo5P2O23] },4.5H2O （1） and {[Cu（o-phen）（H2O）]2[Mo5Se2O2t} （2） （o-phen= 1,10-phenanthroline） have been synthesized by the hydrothermal reaction and structurally characterized by IR spectra and single crystal X-ray diffraction analysis. Their crystal structure determination reveals that the adjacent [Mo5P2O23]^6- or [Mo5Se2O21]^4- anions for the two molecular structures are joined by two bridging [Cu（o-phen）（H2O）] units, thus making up a one dimensional chain in a wind-mill and double-side bridging style, respectively. In the lattice of compound 1, the bimetallic chains are linked through several hydrogen bonds to form a layer-like packing structure. The matching relationship between heteropolyoxomolybdate anion and secondary metal-ligand subunit was also discussed.
