The material described by Mg(MoO2)2 crystallizes in the orthorhombic Pbcm space group. Mg(1) is bonded in a 6-coordinate geometry to two equivalent O(3) and four equivalent O(1) atoms. Mo(1) is bonded to one O(3), two equivalent O(2), and three equivalent O(1) atoms to form a mixture of corner and edge-sharing MoO6 octahedra. The corner-sharing octahedral tilt angles range from 0-64°. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and three equivalent Mo(1) atoms to form distorted OMg2Mo3 trigonal bipyramids that share corners with five equivalent O(3)Mg2Mo2 tetrahedra, corners with two equivalent O(1)Mg2Mo3 trigonal bipyramids,  an edgeedge with one O(3)Mg2Mo2 tetrahedra, and edges with five equivalent O(1)Mg2Mo3 trigonal bipyramids. In the second O site, O(2) is bonded in a square co-planar geometry to four equivalent Mo(1) atoms. In the third O site, O(3) is bonded to two equivalent Mg(1) and two equivalent Mo(1) atoms to form OMg2Mo2 tetrahedra that share corners with two equivalent O(3)Mg2Mo2 tetrahedra, corners with ten equivalent O(1)Mg2Mo3 trigonal bipyramids, and edges with two equivalent O(1)Mg2Mo3 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
