Abstract

The presence of MgB12H12 has often been considered as the major obstacle for the reversible hydrogen storage in Mg(BH4)(2). This communication provides evidence that the MgB12H12 phase (or [B12H12](2-) monomer) does not exist in the decomposition products of Mg(BH4)(2) at temperatures ranging from 265 to 400 degrees C, and thereby it will not act as a dead end.
