The compound described by Mg2Mo2O5 crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Mg sites. In the first Mg site, Mg(1) is bonded to two equivalent O(3) and two equivalent O(5) atoms to form distorted corner-sharing MgO4 trigonal pyramids. In the second Mg site, Mg(2) is bonded to two equivalent O(2) and two equivalent O(4) atoms to form corner-sharing MgO4 tetrahedra. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a see-saw-like geometry to one O(1), one O(3), and two equivalent O(5) atoms. In the second Mo site, Mo(2) is bonded in a see-saw-like geometry to one O(1), one O(2), and two equivalent O(4) atoms. There are five inequivalent O sites. In the first O site, O(1) is bonded in a linear geometry to one Mo(1) and one Mo(2) atom. In the second O site, O(2) is bonded in a trigonal planar geometry to two equivalent Mg(2) and one Mo(2) atom. In the third O site, O(3) is bonded in a trigonal planar geometry to two equivalent Mg(1) and one Mo(1) atom. In the fourth O site, O(4) is bonded to two equivalent Mg(2) and two equivalent Mo(2) atoms to form corner-sharing OMg2Mo2 tetrahedra. In the fifth O site, O(5) is bonded to two equivalent Mg(1) and two equivalent Mo(1) atoms to form corner-sharing OMg2Mo2 tetrahedra. is represented by the CIF card [CIF]
