中文摘要：
采用水热法合成了2个新的混合羧酸铈多孔金属-有机骨架配合物[Ce2（fum）3（H2O）4·（H2bdc）·（H2O）2]n（1,H2fum=富马酸,H2bdc=对苯二甲酸）和[Ce2（suc）2（ox）（H2O）4·（H2O）4]n（2,H2suc=丁二酸,H2ox=草酸）,利用元素分析、红外光谱、热分析和单晶X射线衍射对其组成和结构进行了表征,并研究了其磁学性质.单晶X射线衍射结果表明,配合物1和2均具有三维柱层式多孔金属-有机骨架结构.配合物1由Ce离子和富马酸形成层状结构,层与层之间再通过富马酸作为柱状配体支撑形成三维结构,并在层间的两个方向上形成相互交错的通道,未配位的中性对苯二甲酸分子和晶格水分子填充于孔道中.与配合物1类似,配合物2由Ce离子和丁二酸形成层,层间通过草酸作为柱状配体支撑形成三维结构,在层间的3个方向上具有相互交错的通道,晶格水分子填充于孔道中.
英文摘要：
Two new cerium mixed carboxylate porous metal-organic frameworks,[Ce2（fum）3（H2O）4·（H2bdc）·（H2O）2]n（1,H2fum=fumaric acid,H2bdc=p-benzenedicarboxylic acid） and [Ce2（suc）2（ox）（H2O）4·（H2O）4]n（2,H2suc=succinic acid,H2ox=oxalic acid） were synthesized by hydrothermal method with two kinds of carboxylic acid,respectively.They were characterized by elemental analysis,IR,TGA-DTA and single-crystal X-ray diffraction.Complexes 1 and 2 are both 3D porous metal-organic frameworks of pillared-layer type.Complex 1 possesses a 3D framework structure consisting of Ce-fumarate layers pillared by fumarate ligands with intersected channels in two directions between the layers occupied by uncoordinated neutral p-benzenedicarboxylic acid and lattice water molecules.Similar to complex 1,complex 2 is a 3D framework structure with Ce-succinate layers pillared by oxalate ligands,which shows intersected channels in three directions between the layers filled with lattice water molecules.
