InSO5 crystallizes in the orthorhombic Pnma space group. In(1) is bonded to one O(3), one O(4), two equivalent O(1), and two equivalent O(2) atoms to form InO6 octahedra that share corners with two equivalent In(1)O6 octahedra and corners with four equivalent S(1)O4 tetrahedra. The corner-sharing octahedral tilt angles are 42°. S(1) is bonded to one O(3), one O(4), and two equivalent O(1) atoms to form SO4 tetrahedra that share corners with four equivalent In(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 35-39°. There are four inequivalent O sites. In the first O site, O(1) is bonded in a bent 150 degrees geometry to one In(1) and one S(1) atom. In the second O site, O(2) is bonded in a bent 150 degrees geometry to two equivalent In(1) atoms. In the third O site, O(3) is bonded in a bent 150 degrees geometry to one In(1) and one S(1) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one In(1) and one S(1) atom.

The corner-sharing octahedral tilt angles are 42°. The In(1)-O(3) bond length is 2.23 Å. The In(1)-O(4) bond length is 2.23 Å. Both In(1)-O(1) bond lengths are 2.17 Å. There is one shorter (2.12 Å) and one longer (2.13 Å) In(1)-O(2) bond length.
