FeSnO3 is Ilmenite structured and crystallizes in the triclinic P-1 space group. Fe(1) is bonded in a 5-coordinate geometry to one O(1), two equivalent O(2), and two equivalent O(3) atoms. Sn(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing SnO6 octahedra. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Fe(1) and two equivalent Sn(1) atoms. In the second O site, O(2) is bonded to two equivalent Fe(1) and two equivalent Sn(1) atoms to form edge-sharing OFe2Sn2 trigonal pyramids. In the third O site, O(3) is bonded in a rectangular see-saw-like geometry to two equivalent Fe(1) and two equivalent Sn(1) atoms.
