摘　　要：A novel Nd（Ⅲ） compound,[Nd3（OH）7（O2CC6H4SO3）（H2O）]n·nH2O 1,has been synthesized by the hydrothermal reaction of Nd2O3 and 3-sulfobenzoic acid monosodium salt. It was characterized by IR spectroscopy,elemental analysis,thermogravimetric analysis and single-crystal X-ray diffraction. It crystallizes in monoclinic,space group P21/c with a = 13.024（3）,b = 10.961（2）,c = 12.792（3） ,β = 91.271（3）°,V = 1825.6（7） 3,Z = 4,Mr = 787.97,Dc = 2.867 g/cm3,μ = 8.584 mm-1,F（000） = 1460,S = 1.035,R = 0.0442 and wR = 0.1166 （I 〉 2σ（I））. In this compound,the cross-linkage of Nd atoms by bridging hydroxy groups results in a Nd-O inorganic 〈200〉 layer,and such layers are linked by the 3-O3S-C6H4-CO2 dianions into a pillar-layered structure. The lattice water molecules are located in the cavity.A novel Nd（Ⅲ） compound,[Nd3（OH）7（O2CC6H4SO3）（H2O）]n·nH2O 1,has been synthesized by the hydrothermal reaction of Nd2O3 and 3-sulfobenzoic acid monosodium salt.
