Materials Data on K2RuO5 by Materials Project

Abstract

K2RuO5 crystallizes in the orthorhombic P2_12_12_1 space group. The structure is three-dimensional. there are two inequivalent K sites. In the first K site, K is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of K–O bond distances ranging from 2.68–3.09 Å. In the second K site, K is bonded in a 5-coordinate geometry to seven O atoms. There are a spread of K–O bond distances ranging from 2.66–3.18 Å. Ru is bonded in a trigonal bipyramidal geometry to five O atoms. There are a spread of Ru–O bond distances ranging from 1.77–1.84 Å. There are five inequivalent O sites. In the first O site, O is bonded in a 1-coordinate geometry to three K and one Ru atom. In the second O site, O is bonded in a 5-coordinate geometry to four K and one Ru atom. In the third O site, O is bonded in a 1-coordinate geometry to two K and one Ru atom. In the fourth O site, O is bonded in a 1-coordinate geometry to three K and one Ru atom. In the fifth O site, O is bonded in a 1-coordinate geometry to three K and one Ru atom.
