摘要：
The complex water containing chloride [(CH3)(2)NH2] [NdCl4(H2O)(2)] was prepared for the first time and the crystal structure was determined by X-ray methods from single crystals. The compound crystallizes in the orthorhombic space group Cmca (Z = 8) with a = 1793.5(2) pm, b = 936.6(2) pm and c = 1232.8(2) pm. The anionic part of the structure is built up by chains of edge connected [NdCl4/2Cl2(H2O)(2)](-) trigondodecahedra. In order to study the interactions between the neodymium cation and the ligands magnetic measurements were carried out. The magnetic data were interpreted by ligand field calculations applying the angular overlap model.
