Materials Data on SrCr2O10 by Materials Project

Abstract

SrCr2O10 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr is bonded in a 6-coordinate geometry to ten O atoms. There are a spread of Sr–O bond distances ranging from 2.49–3.31 Å. There are two inequivalent Cr sites. In the first Cr site, Cr is bonded to four O atoms to form corner-sharing CrO4 tetrahedra. There are a spread of Cr–O bond distances ranging from 1.63–1.77 Å. In the second Cr site, Cr is bonded to four O atoms to form corner-sharing CrO4 tetrahedra. There is three shorter (1.64 Å) and one longer (1.77 Å) Cr–O bond length. There are ten inequivalent O sites. In the first O site, O is bonded in a distorted bent 150 degrees geometry to one Sr and one Cr atom. In the second O site, O is bonded in a distorted bent 150 degrees geometry to one Sr and one Cr atom. In the third O site, O is bonded in a bent 120 degrees geometry to one Sr and one O atom. The O–O bond length is 1.23 Å. In the fourth O site, O is bonded in a single-bond geometry to one Cr atom. In the fifth O site, O is bonded in a single-bond geometry to two equivalent Sr atoms. In the sixth O site, O is bonded in a distorted single-bond geometry to one Sr and one Cr atom. In the seventh O site, O is bonded in a distorted single-bond geometry to two equivalent Sr and one O atom. The O–O bond length is 1.24 Å. In the eighth O site, O is bonded in a bent 150 degrees geometry to one Sr and one Cr atom. In the ninth O site, O is bonded in a bent 150 degrees geometry to two Cr atoms. In the tenth O site, O is bonded in a bent 150 degrees geometry to one Sr and one Cr atom.
