The compound described by MgSb2O4 crystallizes in the orthorhombic Pbcm space group. Mg(1) is bonded in a 5-coordinate geometry to one O(3) and four equivalent O(1) atoms. Sb(1) is bonded in a 4-coordinate geometry to one O(2), one O(3), and two equivalent O(1) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Mg(1) and two equivalent Sb(1) atoms to form a mixture of distorted edge and corner-sharing OMg2Sb2 tetrahedra. In the second O site, O(2) is bonded in a distorted water-like geometry to two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a trigonal planar geometry to one Mg(1) and two equivalent Sb(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
