This issue was brought to our attention by the editorial board on behalf of the authors of the above paper and we wish to express regret for not including it in the list of references. We were aware of this work during our research and the citation was indeed included in earlier versions of the manuscript during its preparation. Unfortunately, the reference was accidently removed during subsequent revisions, and this oversight has been carried over into the published paper.

The study by Pistidda et al. reports the synthesis of Mg(BH4)2 exclusively by reactive ball milling of MgB2 at room temperature under 100 bar of hydrogen and characterization of the obtained amorphous product via NMR. This work should have been cited along with references 8a-c in the introduction section. The results reported by Pistidda et al. agree well with some of the data in Figure 2 of our paper and this fact should have been duly acknowledged in the discussion of this figure. We have further examined the effects of hydrogen pressure, milling time, and milling energy (as ball to sample ratio) onto the reaction progress, intermediate species, and final products. Based on these analyses we have tried to provide detailed insights into the reaction mechanism. We also demonstrated the possibility to regenerate the dehydrogenated product through reactive milling.
