Prof. Sesha S. Srinivasan of Tuskegee University kindly suggested that we offer Magnesium Borohydride (Aldrich Prod. No. 715247) as a material for alternative energy applications.1 This complex metal hydride, produced by Aldrich Materials Science R&D, is a base-material for advanced energy storage systems with potential for fulfilling the United States Department of Energy's hydrogen storage goals.2 Magnesium borohydride crystallizes in a hexagonal phase that is stable at room temperature. At 185 °C, the material converts to an orthorhombic phase, which persists and is stable upon cooling back to room temperature. Both phases consist of complex networks of cornersharing tetrahedra including a central Mg atom and four BH4 units.3
