The compound described by MgV3CrO10 crystallizes in the orthorhombic Pmm2 space group. Mg(1) is bonded in a 4-coordinate geometry to two equivalent O(1) and two equivalent O(3) atoms. There are three inequivalent V sites. In the first V site, V(1) is bonded to one O(2), two equivalent O(3), and two equivalent O(4) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent V(3)O4 tetrahedra and corners with two equivalent Cr(1)O4 tetrahedra. In the second V site, V(2) is bonded to one O(6), two equivalent O(1), and two equivalent O(5) atoms to form distorted VO5 trigonal bipyramids that share corners with two equivalent V(3)O4 tetrahedra and corners with two equivalent Cr(1)O4 tetrahedra. In the third V site, V(3) is bonded to two equivalent O(4) and two equivalent O(5) atoms to form corner-sharing VO4 tetrahedra. Cr(1) is bonded to two equivalent O(1) and two equivalent O(3) atoms to form CrO4 tetrahedra that share corners with two equivalent V(1)O5 trigonal bipyramids and corners with two equivalent V(2)O5 trigonal bipyramids. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted T-shaped geometry to one Mg(1), one V(2), and one Cr(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one V(1) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Mg(1), one V(1), and one Cr(1) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one V(1) and one V(3) atom. In the fifth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one V(2) and one V(3) atom. In the sixth O site, O(6) is bonded in a single-bond geometry to one V(2) atom. is represented by the CIF card [CIF]
