DEFINITIVE CRYSTAL-STRUCTURES OF ORTHO-CARBORANE, META-CARBORANE AND PARA-CARBORANE - SUPRAMOLECULAR STRUCTURES DIRECTED SOLELY BY C-H-CENTER-DOT-CENTER-DOT-CENTER-DOT-O HYDROGEN-BONDING TO HMPA (HMPA EQUALS HEXAMETHYLPHOSPHORAMIDE)

Davidson et al., DEFINITIVE CRYSTAL-STRUCTURES OF ORTHO-CARBORANE, META-CARBORANE AND PARA-CARBORANE - SUPRAMOLECULAR STRUCTURES DIRECTED SOLELY BY C-H-CENTER-DOT-CENTER-DOT-CENTER-DOT-O HYDROGEN-BONDING TO HMPA (HMPA EQUALS HEXAMETHYLPHOSPHORAMIDE), Chemical communications, (19), 1996, pp. 2285-2286
Cocrystallisation of ortho- meta- and para-carboranes with hmpa (hexam
ethylphosphoramide) results in the isolation of 1:1 carborane,hmpa add
ucts which provide the first definitive X-ray structures of the unsubs
tituted carboranes as part of three very different C-H...O hydrogen-bo
nded supramolecular structures.
