The structure described by Mg(MoO2)2 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. Mg(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form MgO6 octahedra that share corners with six equivalent Mo(1)O4 tetrahedra, edges with two equivalent Mg(1)O6 octahedra, and edges with four equivalent Mo(2)O6 octahedra. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted MoO4 tetrahedra that share corners with six equivalent Mg(1)O6 octahedra and corners with six equivalent Mo(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 45-66°. In the second Mo site, Mo(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form MoO6 octahedra that share corners with six equivalent Mo(1)O4 tetrahedra, edges with two equivalent Mo(2)O6 octahedra, and edges with four equivalent Mg(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a rectangular see-saw-like geometry to two equivalent Mg(1), one Mo(1), and one Mo(2) atom. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to one Mg(1), one Mo(1), and two equivalent Mo(2) atoms. is represented by the CIF file [CIF]
