title: (2,4,6-Trimethyl-phen-yl)boronic acid-triphenyl-phosphine oxide (1/1).
abstract: In the crystal structure of the title compound, C(9)H(13)BO(2)·C(18)H(15)OP, there are O-H⋯O hydrogen bonds between the O atom of triphenyl-phosphine oxide and one hy-droxy group of the boronic acid. Boronic acid mol-ecules form inversion-related hydrogen-bonded dimers in an R(2) (2)(8) motif. The structure is consolidated by inter-molecular C-H⋯O bonds and C-H⋯π inter-actions.
