Trimesityltin bromide reacts with concentrated aqueous ammonia to give trimesityltin hydroxide.This compound eliminates mesitylen and yields dimesityltin oxide.The product was investigated by 13C NMR, mass spectroscopy and X-ray diffractions.Dimesityltinoxide crystallizes in the space group P21/n with a = 25.38(1) Angstroem, b = 12.525(5) Angstroem, c = 32.91(1) Angstroem, β = 91.37(3) deg and two molecules in the asymmetric unit (Z = 8).The R-factor is 0.049 for 4688 symmetry-independent reflections.The trimeric molecules have six-membered tin-oxygen heterocycles in a twist conformation. - Key words: Organo-Tin-Oxygen Compounds, X-ray
