The di-t-butyltin hydroxide halides t-Bu2Sn(OH)X (X = F, Cl or Br) have been prepared starting from the dihalides t-Bu2SnX2 or the oxide (t-Bu2SnO)3.X-Ray analysis of the three compounds show dimeric molecules: two 5-coordinated tin atoms and the oxygen atoms of the hydroxyl groups are linked to a four-membered ring.As confirmed by the IR spectra, the molecules in the crystal are held together by O-H...X hydrogen bonds.These are strong in the hydroxide fluoride but are weak in the analogous chloride and bromide.
