Abstract:	The synthesis and characterization by ¹H, ¹³C, ¹¹⁹Sn NMR and ¹¹⁹Sn Mössbauer spectroscopy of (Z)-1-[2-(triphenylstannyl)vinyl]-1-cycloheptanol, Full-size image (1), and (Z)-1-[2-tri-p-tolylstannyl)vinyl-1-cycloheptanol, Full-size image (2), are described, together with their halodemetallation by I₂, Br₂ and ICIl to yield derivatives of the types Full-size image (Ar = phenyl or p-tolyl, N = 1, 2; X = I, Br, Cl, respectively). The solid-state structures of four compounds have been determined by X-ray diffraction analysis. In the crystals of Full-size image (1) and Full-size image (2) the Sn atom has a tetrahedral geometry distorted towards trigonal bipyramid as a consequence of a close intramolecular contact with the hydroxyl O(1) atom of 2.742(3) Å and 2.768(3) Å, respectively. A trigonal bipyramidal geometry is found in Full-size image (12) and Full-size image (4), in which significant Sn---O(1) interactions are noted [2.437(8) Å and 2.407(8) Å, respectively].
