Synthesis, spectral investigation, and X-ray diffraction study of the (Cl3C
2N2S2)(+)(UCl6)(-) and [UCl2(OPCl3)(6)](2+)(UCl6)(2)(-) complexes were cond
ucted. Two types of uranium coordination polyhedra were found in the comple
xes studied: an octahedron (six chlorine atoms in the coordination sphere)
and a two-cap trigonal prism (six oxygen atoms of OPCl3 groups at the prism
vertices and two chlorine atoms centering the tetragonal faces).
