Materials Data on NaCaVO4 by Materials Project
NaCaVO4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Na1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.32 Å) and two longer (2.49 Å) Na–O bond lengths. Ca2+ is bonded to six O2- atoms to form CaO6 octahedra that share corners with six equivalent VO4 tetrahedra and edges with two equivalent CaO6 octahedra. There are two shorter (2.34 Å) and four longer (2.40 Å) Ca–O bond lengths. V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with six equivalent CaO6 octahedra. The corner-sharing octahedra tilt angles range from 44–53°. There is two shorter (1.72 Å) and two longer (1.78 Å) V–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Ca2+, and one V5+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to one Na1+, two equivalent Ca2+, and one V5+ atom.
