Materials Data on Sr2LiGe3 by Materials Project

Abstract

LiSr2Ge3 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Li is bonded in a 3-coordinate geometry to one Sr and five Ge atoms. The Li–Sr bond length is 3.46 Å. There are a spread of Li–Ge bond distances ranging from 2.81–2.94 Å. There are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Sr–Ge bond distances ranging from 3.10–3.34 Å. In the second Sr site, Sr is bonded in a 5-coordinate geometry to one Li and nine Ge atoms. There are a spread of Sr–Ge bond distances ranging from 3.32–3.54 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Li, five Sr, and two Ge atoms. There are one shorter (2.50 Å) and one longer (2.52 Å) Ge–Ge bond lengths. In the second Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Li, five Sr, and two Ge atoms. The Ge–Ge bond length is 2.62 Å. In the third Ge site, Ge is bonded in a 1-coordinate geometry to one Li, six Sr, and two Ge atoms. The Ge–Ge bond length is 2.66 Å.
