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-HO hydrogen bonds into a three-dimensional framework, with large channels along ,  and  directions. The [C8H18N]+ cations reside in the channels, interacting with the framework through N-HO hydrogen bonds.
