MgV2O5 crystallizes in the orthorhombic Pmmn space group. Mg(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. V(1) is bonded to one O(1), one O(3), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing VO5 trigonal bipyramids. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent V(1) atoms to form corner-sharing OMg2V2 tetrahedra. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1) and three equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Mg(1) and one V(1) atom.
MgV2O5 crystallizes in the orthorhombic Pmmn space group. Mg(1) is bonded in a 8-coordinate geometry to two equivalent O(1), two equivalent O(2), and four equivalent O(3) atoms. Both Mg(1)-O(1) bond lengths are 2.11 Å. Both Mg(1)-O(2) bond lengths are 2.39 Å. All Mg(1)-O(3) bond lengths are 2.46 Å. V(1) is bonded to one O(1), one O(3), and three equivalent O(2) atoms to form a mixture of distorted corner and edge-sharing VO5 trigonal bipyramids. The V(1)-O(1) bond length is 1.96 Å. The V(1)-O(3) bond length is 1.68 Å. There are two shorter (1.93 Å) and one longer (2.03 Å) V(1)-O(2) bond length. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent V(1) atoms to form corner-sharing OMg2V2 tetrahedra. In the second O site, O(2) is bonded in a distorted see-saw-like geometry to one Mg(1) and three equivalent V(1) atoms. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Mg(1) and one V(1) atom.
