The material described by SmSbO4 crystallizes in the monoclinic P2_1/c space group. Sm(1) is bonded in a 8-coordinate geometry to one O(2), one O(4), three equivalent O(1), and three equivalent O(3) atoms. Sb(1) is bonded to one O(1), one O(3), two equivalent O(2), and two equivalent O(4) atoms to form corner-sharing SbO6 octahedra. The corner-sharing octahedral tilt angles range from 37-45°. There are four inequivalent O sites. In the first O site, O(1) is bonded to three equivalent Sm(1) and one Sb(1) atom to form a mixture of distorted edge and corner-sharing OSm3Sb tetrahedra. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to one Sm(1) and two equivalent Sb(1) atoms. In the third O site, O(3) is bonded in a 4-coordinate geometry to three equivalent Sm(1) and one Sb(1) atom. In the fourth O site, O(4) is bonded in a 3-coordinate geometry to one Sm(1) and two equivalent Sb(1) atoms. is represented by the CIF file [CIF]
