ZnSnO3 is Orthorhombic Perovskite structured and crystallizes in the orthorhombic Pnma space group. Zn(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form distorted ZnO4 tetrahedra that share corners with eight equivalent Sn(1)O6 octahedra and corners with two equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles range from 63-83°. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra and corners with eight equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 47°. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Zn(1) and two equivalent Sn(1) atoms to form distorted corner-sharing OZn2Sn2 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Zn(1) and two equivalent Sn(1) atoms.

The corner-sharing octahedral tilt angles range from 63-83°. There is one shorter (2.08 Å) and one longer (2.13 Å) Zn(1)-O(1) bond length. Both Zn(1)-O(2) bond lengths are 2.03 Å. Sn(1) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form SnO6 octahedra that share corners with six equivalent Sn(1)O6 octahedra and corners with eight equivalent Zn(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 47°. Both Sn(1)-O(1) bond lengths are 2.16 Å. There are two shorter (2.06 Å) and two longer (2.09 Å) Sn(1)-O(2) bond lengths. There are two inequivalent O sites. In the first O site, O(1) is bonded to two equivalent Zn(1) and two equivalent Sn(1) atoms to form distorted corner-sharing OZn2Sn2 tetrahedra. In the second O site, O(2) is bonded in a trigonal planar geometry to one Zn(1) and two equivalent Sn(1) atoms.
