Preservation of crystallinity

OH- HB. One can assnme that these dihydrogen bonds play a principal role in the formation of these dimer structures. Finally, the authors demonstrated that these dihydrogen bonds provide preservation of crystallinity during O-H H-B conversion into O-B bonds with H2 elimination. In fact, solid-state decomposition of NaBHt THEC and other systems leads to a crystalline covalent product by a crystal-to-crystal process.
