Title: Materials Data on SrTiGeO5 by Materials Project

Abstract

SrTiGeO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.48–2.68 Å. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with two equivalent TiO6 octahedra and corners with four equivalent GeO4 tetrahedra. The corner-sharing octahedral tilt angles are 32°. There are a spread of Ti–O bond distances ranging from 1.79–2.05 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four equivalent TiO6 octahedra. The corner-sharing octahedra tilt angles range from 35–55°. All Ge–O bond lengths are 1.78 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Ti4+, and one Ge4+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Sr2+, one Ti4+, and one Ge4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+, one Ti4+, and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Sr2+ andmore » two equivalent Ti4+ atoms. In the fifth O2- site, O2- is bonded to two equivalent Sr2+, one Ti4+, and one Ge4+ atom to form distorted edge-sharing OSr2TiGe tetrahedra.« less
