Title: Materials Data on KMgH9(CO5)2 by Materials Project

Abstract

KMgH9(CO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to four H1+ and ten O2- atoms. There are two shorter (2.91 Å) and two longer (2.94 Å) K–H bond lengths. There are a spread of K–O bond distances ranging from 2.89–3.36 Å. Mg2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.09–2.11 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.28–1.33 Å. There are five inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a linear geometry to two equivalent O2- atoms. Both H–O bond lengths are 1.22 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.01 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one K1+ and one O2- atom. The H–O bond length is 1.00more » Å. In the fifth H1+ site, H1+ is bonded in a distorted single-bond geometry to one K1+ and one O2- atom. The H–O bond length is 1.00 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one C4+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one K1+ and one C4+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one K1+, one Mg2+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one Mg2+, and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one Mg2+, and two H1+ atoms.« less
