Abstract
The structure of the title compound has been determined by single-crystal X-ray diffraction methods from diffractometer data and refined to R 0.093. Crystals are monoclinic, space group P21/n with a0= 15.404(5), b0= 13.552(5), c0= 10.868(5)Å, β= 93.64(5)°, Z= 4. The uranium atoms are surrounded by five chlorine atoms (U–Cl 2.47–2.50 Å) and one oxygen atom (U–O 2.11 Å) at the vertices of a distorted octahedron. Results are discussed in relation to spectral properties of UCl5·tppo, for which optical absorption bands are assigned to transitions from the Γ7, ground state, and hexachlorouranates(V).Keywords
