(Z)-1-(tri-o-tolylstannyl)-3-phenyl-1-buten-3-ol (1) and (Z)-1-(tri-p-tolylstannyl)-3-phenyl-1-buten-3-ol (2) were synthesized by the additive reaction of 3-phenyl-1-butyn-3-ol with tri-o-tolyltin and tri-p-tolyltin hydrides. One of the aryl groups in compounds 1 and 2 was substituted by Cl, Br, I to yield derivatives of the type PhC(CH 3)(OH)CH=CHSn(aryl)2X [aryl=o-tolyl, X = Cl (3); aryl = p-tolyl, X = Cl (4); aryl = o-tolyl, X = Br (5); aryl = p-tolyl, X = Br (6); aryl = o-tolyl, X = I (7); aryl = p-tolyl, X = I (8)]. Compounds 1-8 were characterized by elemental analysis, 1H NMR and FT-IR spectroscopy. The crystal structures of 1, 2 and 5 have been determined by single crystal X-ray diffraction analysis. The Sn atom in 1 and 2 exhibits tetrahedral geometry distorted towards trigonal bipyramidal due to a weak intramolecular interaction between Sn and the hydroxyl O atoms [2.879(5) and 2.859(4) ?], while the Sn atom in 5 adopts a trigonal bipyramidal geometry with a significant Sn(1) ← O interaction [2.483(4) ?].
