Materials Data on K2SnCl4O by Materials Project

Abstract

K2SnOCl4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to one O2- and seven Cl1- atoms. The K–O bond length is 2.82 Å. There are a spread of K–Cl bond distances ranging from 3.25–3.57 Å. Sn4+ is bonded in a distorted trigonal bipyramidal geometry to one O2- and four Cl1- atoms. The Sn–O bond length is 1.91 Å. There are a spread of Sn–Cl bond distances ranging from 2.45–2.65 Å. O2- is bonded in a 3-coordinate geometry to two equivalent K1+ and one Sn4+ atom. There are three inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a 1-coordinate geometry to four equivalent K1+ and one Sn4+ atom. In the second Cl1- site, Cl1- is bonded in a 1-coordinate geometry to three equivalent K1+ and one Sn4+ atom. In the third Cl1- site, Cl1- is bonded in a 5-coordinate geometry to four equivalent K1+ and one Sn4+ atom.
