The structure described by V3CrO8 is trigonal omega-derived structured and crystallizes in the triclinic P1 space group. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(2), one O(3), one O(4), one O(5), one O(6), and one O(8) atom to form VO6 octahedra that share edges with two equivalent V(2)O6 octahedra, edges with two equivalent V(3)O6 octahedra, and edges with two equivalent Cr(1)O6 octahedra. In the second V site, V(2) is bonded to one O(1), one O(3), one O(4), one O(5), one O(6), and one O(7) atom to form VO6 octahedra that share edges with two equivalent V(1)O6 octahedra, edges with two equivalent V(3)O6 octahedra, and edges with two equivalent Cr(1)O6 octahedra. In the third V site, V(3) is bonded to one O(1), one O(2), one O(3), one O(5), one O(7), and one O(8) atom to form VO6 octahedra that share edges with two equivalent V(1)O6 octahedra, edges with two equivalent V(2)O6 octahedra, and edges with two equivalent Cr(1)O6 octahedra. Cr(1) is bonded to one O(1), one O(2), one O(4), one O(6), one O(7), and one O(8) atom to form CrO6 octahedra that share edges with two equivalent V(1)O6 octahedra, edges with two equivalent V(2)O6 octahedra, and edges with two equivalent V(3)O6 octahedra. There are eight inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal non-coplanar geometry to one V(2), one V(3), and one Cr(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one V(3), and one Cr(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one V(1), one V(2), and one V(3) atom. In the fourth O site, O(4) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one V(2), and one Cr(1) atom. In the fifth O site, O(5) is bonded in a distorted T-shaped geometry to one V(1), one V(2), and one V(3) atom. In the sixth O site, O(6) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one V(2), and one Cr(1) atom. In the seventh O site, O(7) is bonded in a distorted trigonal non-coplanar geometry to one V(2), one V(3), and one Cr(1) atom. In the eighth O site, O(8) is bonded in a distorted trigonal non-coplanar geometry to one V(1), one V(3), and one Cr(1) atom. is represented by the CIF card [CIF]
