MgFePO4 crystallizes in the tetragonal I-4 space group. Mg(1) is bonded to four equivalent O(1) atoms to form distorted MgO4 tetrahedra that share corners with four equivalent P(1)O4 tetrahedra and corners with four equivalent Fe(1)O4 trigonal pyramids. Fe(1) is bonded to four equivalent O(1) atoms to form distorted FeO4 trigonal pyramids that share corners with four equivalent Mg(1)O4 tetrahedra and corners with four equivalent P(1)O4 tetrahedra. P(1) is bonded to four equivalent O(1) atoms to form PO4 tetrahedra that share corners with four equivalent Mg(1)O4 tetrahedra and corners with four equivalent Fe(1)O4 trigonal pyramids. O(1) is bonded in a distorted trigonal planar geometry to one Mg(1), one Fe(1), and one P(1) atom.
