Abstract :
The crystal structures of three triorganotin(IV) 5-[(E)-2-(4-methylphenyl)-1-diazenyl]-2-hydroxybenzoates, viz., (Me3Sn{O2CC6H3-p-OH[Ndouble bond; length as m-dashN(C6H4-4-CH3)]})n (1), Et3Sn{O2CC6H3-p-OH[Ndouble bond; length as m-dashN(C6H4-4-CH3)]}OH2 (2), and Bz3Sn{O2CC6H3-p-OH[Ndouble bond; length as m-dashN(C6H4-4-CH3)]} (3), have been determined. In the solid state, complex 1 exists as a one-dimensional polymer where a single benzoate ligand bridges adjacent Sn-centers. The Sn-atom is trigonal bipyramidal with the methyl ligands in the equatorial plane and the axial positions being occupied by the carboxyl O-atom from the carboxylate group of one benzoate ligand and the hydroxy O-atom of an adjacent ligand. Complex 2 exists as a monomeric molecule in which the Sn-atom has a slightly distorted trigonal bipyramidal coordination geometry with three ethyl ligands occupying equatorial positions, while the axial positions are occupied by an O-atom of a water molecule and a carboxylate O-atom. Complex 3 has a distorted tetrahedral geometry. The interpretations of the structures are augmented by IR, NMR (1H, 13C, 119Sn), and 119mSn Mössbauer experiments.
