Abstract:	An X-ray diffraction study has shown that t-Bu₂Si(OH)F crystallizes as hydrogen-bonded tetramers. The fluoride ligand does not take part in the hydrogen bonding, which involves OH--O linkages with an OH--O angle of 160°; the O---O---O angles are 89.7(3)°, but the four oxygen atoms are not quite coplanar (space group I $4$ ). The t-BuSiBu-t angle is 120.5(6)°.
