The title molecule in the solid state exists as a cyclic trimer, with B-O(H)-B bridges and a cyclo-hexane-like structure (C2 twist-boat conformation); dissolution in toluene-d8 affords the B(C6F5)2OH monomer, in which the low-temperature 19F NMR data reveal restricted rotation of the OH substituent around the Ar2B-OH bond (Ea = 39 kJ mol-1), as a result of the partial double-bond character of this interaction.
