Structure and Properties of the Thorium Vanadyl Tellurate,
Th(VO2)2(TeO6)(H2O)2. — Title compound (IV) crystallizes in the orthorhombic space
group Pbca with Z = 8 (single crystal XRD at 193 K). Its three-dimensional structure
is constructed from ThO9 tricapped trigonal prisms, VO5 distorted square pyramids,
distorted VO4 tetrahedra, and distorted TeO6 octahedra. Both of the vanadium polyhedra contain V O+2 vanadyl units with two short V=O bond distances. The UV/Vis diffuse
reflectance spectrum of Th(VO2)2(TeO6)(H2O)2 shows vanadyl-based charge-transfer
absorption features. — (SULLENS, T. A.; ALBRECHT-SCHMITT*, T. E.; Inorg.
