Single‐Crystal Structure Determination and Solid‐State NMR Investigations of Lithium Nitridosilicate Li2SiN2 Synthesized by a Precursor Approach Employing Amorphous “Si(CN2)2” (Eur. J. Inorg. Chem. 12/2009)

Abstract

AbstractThe cover picture shows the [SiN2]2– framework of the lithium ion conductor Li2SiN2. The hitherto unknown crystal structure reveals possible Li+ pathways (red channels) for lithium ion conductivity. Li2SiN2 was synthesized from “Si(CN2)2”, highlighted as a promising precursor for nitridosilicates in arc‐welded (top left) tantalum crucibles. The structure was solved from single crystals, and the 7Li MAS solid‐state NMR spectrum (bottom right) is presented. Details are discussed in the article by W. Schnick et al. on p. 1579 ff.
