Materials Data on SrNiGe2 by Materials Project

Abstract

SrNiGe2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Sr is bonded in a 6-coordinate geometry to four equivalent Ni and ten Ge atoms. All Sr–Ni bond lengths are 3.31 Å. There are a spread of Sr–Ge bond distances ranging from 3.25–3.44 Å. Ni is bonded in a 9-coordinate geometry to four equivalent Sr and five Ge atoms. There are a spread of Ni–Ge bond distances ranging from 2.39–2.52 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 1-coordinate geometry to six equivalent Sr, one Ni, and two equivalent Ge atoms. Both Ge–Ge bond lengths are 2.59 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to four equivalent Sr and four equivalent Ni atoms.
