The mol-ecular structure of the title compound, C10H17BO3Si, features an intra-molecular O-H⋯O hydrogen bond; the boronic group group has an exo-endo conformation. In the crystal, the mol-ecules inter-act with each other by O-H⋯O hydrogen bonds, producing centrosymmetric dimers that are linked by weak π-π stacking inter-actions featuring specific short B⋯C contacts [e.g. 3.372 (2) Å], forming an infinite columnar structure aligned along the a-axis direction.
