Materials Data on K2PtO6 by Materials Project

Abstract

K2PtO6 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K is bonded in a 4-coordinate geometry to seven O atoms. There are a spread of K–O bond distances ranging from 2.73–3.13 Å. Pt is bonded in a linear geometry to two equivalent O atoms. Both Pt–O bond lengths are 1.88 Å. There are three inequivalent O sites. In the first O site, O is bonded to four equivalent K and one O atom to form a mixture of edge and corner-sharing OK4O trigonal bipyramids. The O–O bond length is 1.40 Å. In the second O site, O is bonded in a 1-coordinate geometry to two equivalent K, one Pt, and one O atom. In the third O site, O is bonded in a distorted bent 150 degrees geometry to one K and one O atom. The O–O bond length is 1.28 Å.
