Cyclohexyldimethylammonium tetrahydroxypentaborate

Abstract

The title compound, [C8H18N]+·[B5O6(OH)4]−, has been synthesized under mild solvothermal conditions in the presence of N,N-dimethylcyclohexylamine acting as a template. The structure consists of pentaborate [B5O6(OH)4]− anions connected through O—H...O hydrogen bonds into a three-dimensional framework, with large channels along [100], [010] and [001] directions. The [C8H18N]+ cations reside in the channels, interacting with the framework through N—H...O hydrogen bonds.
