Materials Data on SrO10 by Materials Project

Abstract

SrO10 crystallizes in the tetragonal P4/ncc space group. The structure is two-dimensional and consists of two SrO10 sheets oriented in the (0, 0, 1) direction. Sr is bonded in a distorted body-centered cubic geometry to eight O atoms. All Sr–O bond lengths are 2.66 Å. There are four inequivalent O sites. In the first O site, O is bonded in a distorted square co-planar geometry to four equivalent O atoms. All O–O bond lengths are 2.06 Å. In the second O site, O is bonded in a 4-coordinate geometry to four equivalent O atoms. All O–O bond lengths are 2.10 Å. In the third O site, O is bonded in a distorted bent 120 degrees geometry to one Sr and two O atoms. The O–O bond length is 1.28 Å. In the fourth O site, O is bonded in a bent 120 degrees geometry to one Sr and two O atoms.
