Materials Data on Li2PrGe by Materials Project

Li2PrGe crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Li is bonded in a distorted trigonal non-coplanar geometry to four equivalent Pr and three equivalent Ge atoms. There are a spread of Li–Pr bond distances ranging from 3.03–3.11 Å. All Li–Ge bond lengths are 2.61 Å. Pr is bonded in a 8-coordinate geometry to eight equivalent Li and six equivalent Ge atoms. All Pr–Ge bond lengths are 3.50 Å. Ge is bonded in a distorted hexagonal planar geometry to six equivalent Li and six equivalent Pr atoms.
