Materials Data on NbRhO4 by Materials Project
RhNbO4 is Hydrophilite-derived structured and crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with eight equivalent RhO6 octahedra and edges with two equivalent NbO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are two shorter (2.01 Å) and four longer (2.04 Å) Nb–O bond lengths. Rh3+ is bonded to six O2- atoms to form RhO6 octahedra that share corners with eight equivalent NbO6 octahedra and edges with two equivalent RhO6 octahedra. The corner-sharing octahedral tilt angles are 50°. There are four shorter (2.04 Å) and two longer (2.05 Å) Rh–O bond lengths. 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 Rh3+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Nb5+ and two equivalent Rh3+ atoms.
