Materials Data on Li(PrGe)4 by Materials Project

Abstract

Li(PrGe)4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li is bonded in a T-shaped geometry to three Ge atoms. There are a spread of Li–Ge bond distances ranging from 2.83–3.00 Å. There are two inequivalent Pr sites. In the first Pr site, Pr is bonded in a 7-coordinate geometry to seven Ge atoms. There are a spread of Pr–Ge bond distances ranging from 3.09–3.71 Å. In the second Pr site, Pr is bonded in a 6-coordinate geometry to six Ge atoms. There are a spread of Pr–Ge bond distances ranging from 3.00–3.15 Å. There are three inequivalent Ge sites. In the first Ge site, Ge is bonded in a 9-coordinate geometry to two equivalent Li, six Pr, and one Ge atom. The Ge–Ge bond length is 2.57 Å. In the second Ge site, Ge is bonded in a 8-coordinate geometry to seven Pr and one Ge atom. The Ge–Ge bond length is 2.66 Å. In the third Ge site, Ge is bonded in a 8-coordinate geometry to one Li, six Pr, and one Ge atom.
