Materials Data on Li2GePbS4 by Materials Project
Li2PbGeS4 crystallizes in the tetragonal I-42m space group. The structure is three-dimensional. Li1+ is bonded in a distorted square co-planar geometry to four equivalent S2- atoms. All Li–S bond lengths are 2.47 Å. Pb2+ is bonded in a 8-coordinate geometry to eight equivalent S2- atoms. There are four shorter (3.10 Å) and four longer (3.23 Å) Pb–S bond lengths. Ge4+ is bonded in a tetrahedral geometry to four equivalent S2- atoms. All Ge–S bond lengths are 2.24 Å. S2- is bonded in a 3-coordinate geometry to two equivalent Li1+, two equivalent Pb2+, and one Ge4+ atom.
