NASICON-type Na(3)V(2)(PO(4))(3)

Single crystals of the title compound, tris­odium divanadium(III) tris­(orthophosphate), were grown from a self-flux in the system Na(4)P(2)O(7)–NaVP(2)O(7). Na(3)V(2)(PO(4))(3) belongs to the family of NASICON-related structures and is built up from isolated [VO(6)] octa­hedra (3. symmetry) and [PO...

Sumario:Single crystals of the title compound, tris­odium divanadium(III) tris­(orthophosphate), were grown from a self-flux in the system Na(4)P(2)O(7)–NaVP(2)O(7). Na(3)V(2)(PO(4))(3) belongs to the family of NASICON-related structures and is built up from isolated [VO(6)] octa­hedra (3. symmetry) and [PO(4)] tetra­hedra (.2 symmetry) inter­linked via corners to establish the framework anion [V(2)(PO(4))(3)](3−). The two independent Na(+) cations are partially occupied [site-occupancy factors = 0.805 (18) and 0.731 (7)] and are located in channels with two different oxygen environments, viz sixfold coordination for the first ([Image: see text]. symmetry) and eightfold for the second (.2 symmetry) Na(+) cation.
