Abstract

The synthesis and the i.r, and ¹¹⁹Sn Mössbauer spectroscopic characterization of SnEt₂(dapt), SnBuCl(dapt)[H₂dapt = 2,6-diacetylpyridine bis(2-thenoylhydrazone)], and SnBu₂(daps)[H₂daps = 2,6-diacetylpyridine bis(salicyloylhydrazone)] are reported together with the X-ray crystal structure of the first compound. The structure consists of monomeric units in which the tin atom exhibits a nearly pentagonal-bipyramidal co-ordination geometry with the equatorial plane defined by the N₃O₂ donor set of the hydrazone ligand and the two ethyl groups in the apical positions. Some disorder occurs in both the thienyl moieties.
