Materials Data on Sr2LiInGe2 by Materials Project
LiSr2InGe2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li is bonded in a 5-coordinate geometry to one In and four Ge atoms. The Li–In bond length is 3.03 Å. There are a spread of Li–Ge bond distances ranging from 2.80–2.94 Å. There are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 5-coordinate geometry to three equivalent In and five Ge atoms. There are two shorter (3.76 Å) and one longer (3.77 Å) Sr–In bond lengths. There are a spread of Sr–Ge bond distances ranging from 3.23–3.35 Å. In the second Sr site, Sr is bonded in a 5-coordinate geometry to four equivalent In and five Ge atoms. There are two shorter (3.44 Å) and two longer (3.63 Å) Sr–In bond lengths. There are a spread of Sr–Ge bond distances ranging from 3.22–3.27 Å. In is bonded in a 12-coordinate geometry to one Li, seven Sr, and four Ge atoms. There are a spread of In–Ge bond distances ranging from 2.92–2.96 Å. There are two inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to three equivalent Li, four Sr, and two equivalent In atoms. In the second Ge site, Ge is bonded in a 9-coordinate geometry to one Li, six Sr, and two equivalent In atoms.
