Scandium and vanadium borohydride ammoniates: Enhanced dehydrogenation behavior upon coordinative expansion and establishment of Hδ+⋯−δH interactions

Two novel metal borohydride ammoniates-ScLi(BH4)4·4NH3 and V(BH4)3·3NH3 are shown to exhibit superior dehydrogenation performances established upon intensive interactions and balanced stoichiometry of dihydrogen.
