説明
Magnetic susceptibilities of UX4hmpa2 (where X = Cl−, Br− and I−; hmpa = hexamethylphosphoramide) were measured from the b.p. of liquid helium to room temperature. The temperature dependence of the magnetic susceptibilities indicates that UI4hmpa2 has a trans-configuration, as have UCl4hmpa2 and UBr4hmpa2. Analysis of the magnetic susceptibilities on the basis of the ligand-field theory shows the distortion of the ligand field around the central uranium ion from Oh symmetry in the following order: UCl4hmpa2 < UBr4hmpa2 < UI4hmpa2.
