Abstract: | The synthesis and characterization of a new series of hydrated uranium(III) complex chlorides of the general formula M1UCl4-3H2O (M1 K, Rb or NH4) are reported. The compounds crystallize in the monoclinic system. Unit cell parameters were determined from X-ray powder diffraction data. The magnetic susceptibilities of the complex chlorides were measured by the Faraday method in the 4.2–300 K range. The compounds exhibit Curie-Weiss paramagnetism in the 100–300 K range, with the derived effective magnetic moments ranging from 3.57μB to 3.71μB. Solid state electronic and IR spectra were recorded in the 4000–30 000 and 80–4000 cm?1 ranges, respectively and discussed. Non-static high vacuum thermal dehydrations enabled us to obtain the anhydrous compounds KUCl4, RbUCl4 and UCl3. |
