Abstract

A highly complex crystal structure of stoichiometric Mg₅(en)₆(BH₄)₁₀ was solved from single crystal synchrotron X-ray diffraction and confirmed by neutron powder diffraction (NPD) on isotopically substituted Mg(en)_1.2(¹¹BD₄)₂. We highlight the role of the amorphous Mg(BH₄)₂ in the reactivity of the Mg(BH₄)₂-en system and characterized a previously overlooked phase, Mg(en)₂(BH₄)₂.
