Materials Data on K4Ru(NO2)6 by Materials Project

Abstract

Ru(K2(NO2)3)2 crystallizes in the trigonal R-3 space group. The structure is three-dimensional and consists of three rutenio molecules and one K2(NO2)3 framework. In the K2(NO2)3 framework, there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of K–O bond distances ranging from 2.85–3.25 Å. In the second K1+ site, K1+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are three shorter (2.89 Å) and six longer (2.90 Å) K–O bond lengths. N+2.33+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both N–O bond lengths are 1.27 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one N+2.33+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one N+2.33+ atom.
