| Abstract: | Preparation, Crystal Structure, and Magnetism of (CH3)2NH2]PrCl4(H2O)2] The complex water containing chloride (CH3)2NH2]PrCl4(H2O)2] has been prepared for the first time and the crystal structure has been determined from single crystal X‐ray diffraction data. The compound crystallizes orthorhombically in the space group Cmca (Z = 8) with a = 1796.6(2) pm, b = 940.7(1) pm, and c = 1238.4(2) pm. The anionic part of the structure is built up by chains of edge‐connected trigondodecahedra PrCl6(H2O)2]3– according to PrCl4/2Cl2(H2O)2]–, which are held together by dimethylammonium cations ((CH3)2NH2]+). In order to study the interactions between the praseodymium cation (Pr3+) and the ligands magnetic measurements were carried out. The magnetic data were interpreted by ligand field calculations applying the angular overlap model. |
