Abstract

The reactions of sodium amidoborane (NaNH₂BH₃) with NiBr₂ have been investigated, and the results showed that black precipitate 1 including the NiBNH_x composites could be obtained. From the aqueous solution of the precipitate 1, the hydrolysis product Ni-B (2) was isolated and characterized. Both the in situ formed precipitate 1 and the hydrolysis product 2 can catalyze the formation of Na[BH₃(NH₂BH₂)₂H]. CoCl₂ showed comparable performance with NiBr₂. Based on these results, a facile method for the synthesis of Na[BH₃(NH₂BH₂)₂H] has been developed. This work provides insights into studying experimental methods for the synthesis of long B/N chain complexes and developing boron and nitrogen chemistry.
