Uranium(III) chloro complexes of formulae CsUCl4 and Cs2LiUCl6 were synthesized and characterized by electronic absorption, X-ray powder diffraction and magnetic susceptibility investigation. Cs2LiUCl6 crystallizes in the regular system Fm3m, with a=10.671 Å, V=1218.03 Å3 and Z=4. The powder diffraction data for CsUCl4 could not be indexed unambiguously. The following paramagnetic constants were obtained: C=1.215 emu K mol−1, Θ=−32.7 K, μeff=3.13 B.M. (for CsUCl4) and C=1.571 emu K mol−1, Θ=−103 K, μeff=3.56 B.M. (for Cs2LiUCl6). Solid state electronic spectra of the compounds were recorded in the range 4000–30 000 cm−1 and are discussed. An analysis of the 5f3→5f26d1 transitions in the absorption spectrum of Cs2LiUCl6 is presented.
