Abstract

Abstract Subvalent vanadium (I) salts, of empirical formulas, VCl, vanadium (I) chloride and LiVH 2, lithium vanadium (I) dihydride, can be conveniently prepared in THF solution, starting at–78 C, by treating either VCl 3 or VCl 4 with an appropriate number of equivalents of nBuLi. As judged by the stability of solutions or solid samples of LiVH 2, the preparation of LiVH 2 from VCl 4 is the preferred method. Individual physical characterization of solid ...
