Materials Data on NbCrO4 by Materials Project
CrNbO4 is beta Vanadium nitride-derived structured and crystallizes in the orthorhombic Pbcn space group. The structure is three-dimensional. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with four equivalent NbO6 octahedra, corners with six equivalent CrO6 octahedra, and an edgeedge with one CrO6 octahedra. The corner-sharing octahedra tilt angles range from 45–55°. There are a spread of Nb–O bond distances ranging from 1.94–2.12 Å. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six equivalent NbO6 octahedra, an edgeedge with one NbO6 octahedra, and edges with two equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 48–55°. There are a spread of Cr–O bond distances ranging from 1.99–2.03 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Nb5+ and one Cr3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Nb5+ and two equivalent Cr3+ atoms.
