Abstract:
The title compound, nonasodium chromium(III) hexakis[molybdate(VI)], Na 9 Cr(MoO 4 ) 6 was prepared by solid-state reactions. The basic structure units are isolated polyhedral clusters composed of a central CrO 6 octahedron sharing vertices with six MoO 4 tetrahedra to form an open framework in which the Na + cations are bound to the free vertices of the MoO 4 tetrahedra. The Cr 3+ cation has site symmetry of 32 (6 a ), one Na atom sits on a twofold axis (18 e ), and all other atoms are at general positions. The bond-valance-sum model confirms the expected values of ion charges. The title compound is isotypic with Na 9 Sc(MoO 4 ) 6 and Na 9 Fe(MoO 4 ) 6 . It is compared and discussed with similar structures.
