NASICON-type Na3V2(PO4)3
Single crystals of the title compound, tris-odium 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)] octa-hedra (3. symmetry) and [PO(4)] tetra-hedra (.2 symmetry) inter-linked via corners to establish the framework anion [V(2)(PO...
متن کاملRbSn2(PO4)3, a NASICON-type phosphate
The title compound, rubidium ditin(IV) tris-(phosphate), RbSn(2)(PO(4))(3), belongs to the NASICON-type family of phosphates and crystallizes in the space group R[Formula: see text]. The structure is composed of PO(4) tetra-hedra (1 symmetry) and two slightly distorted SnO(6) octa-hedra, both with 3. symmetry, which are inter-linked through corner-sharing O atoms to form a (3) (∞)[Sn(2)(PO(4))(...
متن کاملNa NMR Study of NASICON - type Compounds ,
The structure of NASICON-type compounds, Nai+xScxTi2_z(P04)3 (0 < x < 2), and the dynamics of Na have been investigated by Na NMR spectroscopy. It was found that the Na ID and 2D MQMAS spectra depend on the Na concentration, suggesting strongly that the Na ions are distributed between two crystallographically nonequivalent sites, one is a special position with axial symmetry, and the other a po...
متن کاملNa4Fe2+Fe3+(PO4)3, a new synthetic NASICON-type phosphate
This paper reports the crystal structure of tetra-sodium diiron tris(phosphate), Na(4)Fe(2+)Fe(3+)(PO(4))(3), which has been synthesized hydro-thermally at 773 K and 0.1 GPa. The crystal structure has been refined in the space group Rc and is identical to that of γ-NASICON. The heteropolyhedral framework is based on a regular alternation, in three dimensions, of corner-sharing PO(4) tetra-hedra...
متن کاملNASICON-related Na3.4Mn0.4Fe1.6(PO4)3
The solid solution, sodium [iron(III)/manganese(II)] tris-(orthophosphate), Na₃.₄Mn₀.₄Fe₁.₆(PO₄)₃, was obtained using a flux method. Its crystal structure is related to that of NASICON-type compounds. The [(Mn/Fe)₂(PO₄)₃] framework is built up from an (Mn/Fe)O₆octa-hedron (site symmetry 3.), with a mixed Mn/Fe occupancy, and a PO₄ tetra-hedron (site symmetry .2). The Na⁺ cations are distributed...
