Title: Materials Data on Sr(GaO2)2 by Materials Project

Abstract

SrGa2O4 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 5-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.43–3.10 Å. In the second Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.50–2.85 Å. There are four inequivalent Ga3+ sites. In the first Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.86–1.89 Å. In the second Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.84–1.89 Å. In the third Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. There are a spread of Ga–O bond distances ranging from 1.84–1.91 Å. In the fourth Ga3+ site, Ga3+ is bonded to four O2- atoms to form corner-sharing GaO4 tetrahedra. There is one shorter (1.86 Å) and three longer (1.87 Å) Ga–O bond length. There aremore » eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a trigonal planar geometry to one Sr2+ and two Ga3+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Sr2+ and two Ga3+ atoms. In the third O2- site, O2- is bonded to two Sr2+ and two Ga3+ atoms to form distorted corner-sharing OSr2Ga2 tetrahedra. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two Sr2+ and two Ga3+ atoms. In the fifth O2- site, O2- is bonded to two Sr2+ and two Ga3+ atoms to form distorted corner-sharing OSr2Ga2 trigonal pyramids. In the sixth O2- site, O2- is bonded in a trigonal planar geometry to one Sr2+ and two Ga3+ atoms. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to two Sr2+ and two Ga3+ atoms. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two Sr2+ and two Ga3+ atoms.« less
