Abstract

Abstract : A highly complicated structure of Mg( en )1.2 (BH4 )2 was solved from single crystal synchrotron X-ray diffraction, the new Mg( en )2 (BH4 )2 was shown to be its decomposition intermediate. The role of less reactive amorphous Mg(BH4 )2 was demonstrated. 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 ( 11 BD4 )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 .
