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 four water molecules and two SrO9 sheets oriented in the (0, 0, 1) direction. In each SrO9 sheet, Sr is bonded in a distorted body-centered cubic geometry to eight O atoms. There are four shorter (2.67 Å) and four longer (2.68 Å) Sr–O bond lengths. There are three inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Sr and two O atoms. There is one shorter (1.28 Å) and one longer (2.04 Å) O–O bond length. In the second O site, O is bonded in a bent 120 degrees geometry to one Sr and one O atom. In the third O site, O is bonded in a distorted square co-planar geometry to four equivalent O atoms.
