In2(SO4)3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent In3+ sites. In the first In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six SO4 tetrahedra. There are a spread of In–O bond distances ranging from 2.14–2.21 Å. In the second In3+ site, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six SO4 tetrahedra. There are a spread of In–O bond distances ranging from 2.13–2.18 Å. There are three inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four InO6 octahedra. The corner-sharing octahedra tilt angles range from 30–45°. There is two shorter (1.48 Å) and two longer (1.49 Å) S–O bond length. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four InO6 octahedra. The corner-sharing octahedra tilt angles range from 32–45°. There is two shorter (1.48 Å) and two longer (1.49 Å) S–O bond length. In the third S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four InO6 octahedra. The corner-sharing octahedra tilt angles range from 23–45°. There is two shorter (1.48 Å) and two longer (1.49 Å) S–O bond length. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S6+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one In3+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one In3+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a bent 150 degrees geometry to one In3+ and one S6+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to one In3+ and one S6+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S6+ atom. In the eleventh O2- site, O2- is bonded in a bent 150 degrees geometry to one In3+ and one S6+ atom. In the twelfth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S6+ atom.
