Title: Materials Data on Cu5Si4(HO7)2 by Materials Project

Abstract

Cu5Si4(HO7)2 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. there are three inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.89 Å) and two longer (2.01 Å) Cu–O bond length. In the second Cu2+ site, Cu2+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of Cu–O bond distances ranging from 1.83–1.98 Å. In the third Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.93–1.97 Å. There are two inequivalent Si4+ sites. In the first Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.63–1.65 Å. In the second Si4+ site, Si4+ is bonded to four O2- atoms to form corner-sharing SiO4 tetrahedra. There are a spread of Si–O bond distances ranging from 1.62–1.65 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are seven inequivalent O2- sites. In the first O2- site,more » O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cu2+ and one Si4+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cu2+ and one Si4+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two Si4+ atoms. In the fifth O2- site, O2- is bonded in a trigonal planar geometry to three Cu2+ atoms. In the sixth O2- site, O2- is bonded in a bent 120 degrees geometry to one Si4+ and one H1+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu2+ and one Si4+ atom.« less
