The material described by FeNbO4 is beta Vanadium nitride-derived structured and crystallizes in the tetragonal I-4m2 space group. Nb(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form distorted NbO6 octahedra that share corners with four equivalent Nb(1)O6 octahedra and edges with four equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles are 23°. Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted FeO6 octahedra that share corners with four equivalent Fe(1)O6 octahedra and edges with four equivalent Nb(1)O6 octahedra. The corner-sharing octahedral tilt angles are 28°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to two equivalent Nb(1) and one Fe(1) atom. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one Nb(1) and two equivalent Fe(1) atoms. is represented by the CIF file [CIF]
