Materials Data on SrGe2 by Materials Project
SrGe2 is Magnesium tetraboride-like structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 9-coordinate geometry to nine Ge atoms. There are a spread of Sr–Ge bond distances ranging from 3.23–3.52 Å. In the second Sr site, Sr is bonded in a 11-coordinate geometry to eleven Ge atoms. There are a spread of Sr–Ge bond distances ranging from 3.36–3.63 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 8-coordinate geometry to five Sr and three Ge atoms. There are two shorter (2.58 Å) and one longer (2.64 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 8-coordinate geometry to five Sr and three Ge atoms. Both Ge–Ge bond lengths are 2.59 Å. In the third Ge site, Ge is bonded in a 8-coordinate geometry to five Sr and three Ge atoms. The Ge–Ge bond length is 2.57 Å.
