The material structure described by MgSnBiO4 crystallizes in the tetragonal I-4m2 space group. Mg(1) is bonded in a rectangular see-saw-like geometry to four equivalent O(2) atoms. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 octahedra that share corners with four equivalent Sn(1)O6 octahedra and corners with four equivalent Bi(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 4°. Bi(1) is bonded to four equivalent O(1) atoms to form distorted BiO4 tetrahedra that share corners with four equivalent Sn(1)O6 octahedra and corners with four equivalent Bi(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 65°. There are two inequivalent O sites. In the first O site, O(1) is bonded in a trigonal planar geometry to one Sn(1) and two equivalent Bi(1) atoms. In the second O site, O(2) is bonded in a rectangular see-saw-like geometry to two equivalent Mg(1) and two equivalent Sn(1) atoms. is represented by the CIF card [CIF]
