Abstract
- New convenient procedures for the preparation of ammonia monochloroborane (NH₃BH₂Cl) and cyclotriborazane [(BH₂NH₂)₃] are described. Crystal structures have been determined by single-crystal X-ray diffraction. Strong H...Cl...H bifurcated hydrogen bonding and weak N--H...H dihydrogen bonding are observed in the crystal structure of ammonia monochloroborane. When heated at 50 °C or under vacuum, ammonia monochloroborane decomposes to (NH₂BHCl)x, which was characterized by NMR, elemental analysis, and powder X-ray diffraction. Redetermination of the crystal structure of cyclotriborazane at low temperature by single-crystal X-ray diffraction analysis provides accurate hydrogen positions. Similar to ammonia borane, cyclotriborazane shows extensive dihydrogen bonding of N--H‥H and B--H...H bonds with Hδ+‥Hδ+‥ interactions in the range of 2.00--2.34 A. [ABSTRACT FROM AUTHOR]
