Abstract

SrGeO3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded to eight O2- atoms to form distorted SrO8 hexagonal bipyramids that share corners with two equivalent GeO4 tetrahedra and edges with four GeO4 tetrahedra. There are a spread of Sr–O bond distances ranging from 2.51–2.79 Å. In the second Sr2+ site, Sr2+ is bonded in a distorted body-centered cubic geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.48–2.79 Å. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent GeO4 tetrahedra and edges with two equivalent SrO8 hexagonal bipyramids. There is two shorter (1.73 Å) and two longer (1.83 Å) Ge–O bond length. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share a cornercorner with one SrO8 hexagonal bipyramid, corners with two GeO4 tetrahedra, and an edgeedge with one SrO8 hexagonal bipyramid.
