ABSTRACT:
State-of-the-art electronic structure calculations provide the likelihood of the availability of ScLi3N2, TiLi3N2, VLi3N2, CrLi3N2, MnLi3N2, CoLi3N2, NiLi3N2, CuLi3N2, and ZnLi3N2as compounds for reaction with hydrogen under suitable conditions. Reaction with hydrogen is likely to form stable hydrides of the family ScLi3N2Hn, TiLi3N2Hn, VLi3N2Hn, CrLi3N2Hn, MnLi3N2Hn, FeLi3N2HnCoLi3N2Hn, NiLi3N2Hn, CuLi3N2Hn, and ZnLi3N2Hn, where n is an integer in the range of 1-4. These materials offer utility for hydrogen storage systems.
