Reaction of UX{sub 4} with NaL (L = (C{sub 5}H{sub 5})Co(P(O)(OEt){sub 2}){sub 3}) gave the complexes LUX{sub 3} (X =BH{sub 4} (1), CL (2)). The trichloride 2 reacted with NaL or TlCp (Cp = C{sub 5}H{sub 5}) to afford respectively the compounds L{sub 2}UCl{sub 2} (3) and LCpUCl{sub 2} (4). Crystals of 3 belong to space group P2{sub 1}/c. The unit cell has a = 13.229 (4) {angstrom}, b = 20.011 (2) {angstrom}, c = 21.080 (1) {angstrom}, {beta} = 103.97 (3) {degree}, V = 5415 (3) {angstrom}{sup 3} and contains four molecules. For the 2321 independent reflections with I > 3{sigma}(I), the final conventional and weighted discrepancy factors are 0.052 and 0.054, respectively. The geometry of the UO{sub 6}Cl{sub 2} core is intermediate between a bicapped trigonal prism and a square antiprism. The average U-Cl distance is 2.728 (8) {angstrom}, and the average U-O distance is 2.36 (5) {angstrom}. 17 refs., 3 figs., 3 tabs.
