The material described by FeCoVO4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. V(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form VO4 tetrahedra that share corners with six equivalent Fe(1)O6 octahedra and corners with six equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-59°. Fe(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form FeO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra, edges with two equivalent Fe(1)O6 octahedra, and edges with four equivalent Co(1)O6 octahedra. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent V(1)O4 tetrahedra, edges with two equivalent Co(1)O6 octahedra, and edges with four equivalent Fe(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to one V(1), one Fe(1), and two equivalent Co(1) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one V(1), two equivalent Fe(1), and one Co(1) atom. is represented by the Crystallographic Information File (CIF) [CIF]
