VCr3O8 is trigonal omega-derived structured and crystallizes in the monoclinic C2/m space group. V(1) is bonded to two equivalent O(2) and four equivalent O(3) atoms to form VO6 octahedra that share edges with two equivalent Cr(1)O6 octahedra and edges with four equivalent Cr(2)O6 octahedra. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to two equivalent O(1) and four equivalent O(3) atoms to form distorted CrO6 octahedra that share edges with two equivalent V(1)O6 octahedra and edges with four equivalent Cr(2)O6 octahedra. In the second Cr site, Cr(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form CrO6 octahedra that share edges with two equivalent V(1)O6 octahedra, edges with two equivalent Cr(1)O6 octahedra, and edges with two equivalent Cr(2)O6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one Cr(1) and two equivalent Cr(2) atoms. In the second O site, O(2) is bonded in a distorted T-shaped geometry to one V(1) and two equivalent Cr(2) atoms. In the third O site, O(3) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one Cr(1), and one Cr(2) atom.
