Title: Materials Data on Na2Li18Ge17 by Materials Project

Abstract

Na2Li18Ge17 crystallizes in the trigonal P31m space group. The structure is three-dimensional. there are three inequivalent Na sites. In the first Na site, Na is bonded in a 4-coordinate geometry to four Ge atoms. There are a spread of Na–Ge bond distances ranging from 2.90–3.19 Å. In the second Na site, Na is bonded in a distorted single-bond geometry to four Ge atoms. There are one shorter (3.01 Å) and three longer (3.37 Å) Na–Ge bond lengths. In the third Na site, Na is bonded in a 1-coordinate geometry to four Ge atoms. There are one shorter (3.04 Å) and three longer (3.35 Å) Na–Ge bond lengths. There are thirteen inequivalent Li sites.
