Materials Data on InS3(NO4)3 by Materials Project
(In(SO4)3)2(N2)3 crystallizes in the trigonal R3c space group. The structure is one-dimensional and consists of eighteen ammonia molecules and three In(SO4)3 ribbons oriented in the (0, 0, 1) direction. In each In(SO4)3 ribbon, In3+ is bonded to six O2- atoms to form InO6 octahedra that share corners with six equivalent SO4 tetrahedra. There are three shorter (2.15 Å) and three longer (2.17 Å) In–O bond lengths. S+3.33+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent InO6 octahedra. The corner-sharing octahedra tilt angles range from 30–42°. There are a spread of S–O bond distances ranging from 1.47–1.49 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one In3+ and one S+3.33+ atom. In the second O2- site, O2- is bonded in a bent 150 degrees geometry to one In3+ and one S+3.33+ atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S+3.33+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one S+3.33+ atom.
