Abstract

This article is updated to cover the literature in the area of inorganic chemistry of alkali metals since 2006. The advancement in instrumentation and spectroscopic techniques in recent two decades has provided researchers with more powerful tools for structure determination of compounds. In this respect, mixed-sandwich electrides of alkali metals, complexes with dimers or chains of alkali metal anions, electrides with alkali metal ions intercalated into zeolites, and interstitial hydride enclosed by an unusual (Li+)8 cubic cage and a simpler more defined LiH-containing complex have recently been reported in the literature. Alkali metal ozonides, mixed alkali metal ozonide superoxide, and alkali metal suboxides have also been reported. The preparation of Na3N, K3N, ternary and higher nitride compounds of lithium are included in this article. The exact composition of “NaB6” and “KB6” is also included. The role of alkali metals in trielide clusters of traditional Zintl polyanions has been shown. Synthesis and structures of trimetallic Li–Na–K amide-alkoxide compounds, alkoxide compounds, enolates, and highly aggregated cage structures of lithium-heavier alkali metal alkoxides and heterotrimetallic alkoxide are included.
