MgV(CO3)2 is Calcite-derived structured and crystallizes in the triclinic P-1 space group. Mg(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form distorted MgO6 octahedra that share corners with two equivalent V(1)O6 octahedra and edges with two equivalent V(1)O6 octahedra. The corner-sharing octahedral tilt angles are 31°. V(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form VO6 octahedra that share corners with two equivalent Mg(1)O6 octahedra and edges with two equivalent Mg(1)O6 octahedra. The corner-sharing octahedral tilt angles are 31°. C(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to one Mg(1), one V(1), and one C(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Mg(1), one V(1), and one C(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Mg(1), one V(1), and one C(1) atom.
