FeVO4 is zeta iron carbide-derived structured and crystallizes in the orthorhombic Imma space group. V(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form distorted VO6 octahedra that share corners with eight equivalent Fe(1)O6 octahedra and edges with two equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-51°. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with eight equivalent V(1)O6 octahedra and edges with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-51°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent V(1) and one Fe(1) atom.

The corner-sharing octahedral tilt angles range from 49-51°. Both V(1)-O(1) bond lengths are 1.87 Å. There are two shorter (1.73 Å) and two longer (2.31 Å) V(1)-O(2) bond lengths. Fe(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form FeO6 octahedra that share corners with eight equivalent V(1)O6 octahedra and edges with two equivalent Fe(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-51°. Both Fe(1)-O(2) bond lengths are 2.10 Å. All Fe(1)-O(1) bond lengths are 2.00 Å. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one V(1) and two equivalent Fe(1) atoms. In the second O site, O(2) is bonded in a 3-coordinate geometry to two equivalent V(1) and one Fe(1) atom.
