Materials Data on KTiH2S2O9 by Materials Project
KTiH2S2O9 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. K1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.80–3.17 Å. Ti3+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with five SO4 tetrahedra. There are a spread of Ti–O bond distances ranging from 2.02–2.08 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent TiO6 octahedra. The corner-sharing octahedral tilt angles are 39°. There are a spread of S–O bond distances ranging from 1.45–1.53 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 34–42°. There are a spread of S–O bond distances ranging from 1.46–1.51 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Ti3+, and one S6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to two equivalent K1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one Ti3+, and one S6+ atom. In the fifth O2- site, O2- is bonded in a bent 150 degrees geometry to one Ti3+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent K1+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ti3+ and two H1+ atoms.
