Title: Materials Data on SrGe2 by Materials Project

Abstract

SrGe2 is hexagonal omega structure structured and crystallizes in the trigonal P-3m1 space group. The structure is three-dimensional. Sr is bonded to six equivalent Ge atoms to form SrGe6 octahedra that share corners with six equivalent GeSr3Ge3 octahedra, edges with six equivalent SrGe6 octahedra, and edges with six equivalent GeSr3Ge3 octahedra. The corner-sharing octahedral tilt angles are 18°. All Sr–Ge bond lengths are 3.19 Å. Ge is bonded to three equivalent Sr and three equivalent Ge atoms to form distorted GeSr3Ge3 octahedra that share corners with three equivalent SrGe6 octahedra, corners with three equivalent GeSr3Ge3 octahedra, edges with three equivalent SrGe6 octahedra, and edges with nine equivalent GeSr3Ge3 octahedra. The corner-sharing octahedra tilt angles range from 0–18°. All Ge–Ge bond lengths are 2.61 Å.
