Abstract
Abstract The crystal structures of three triorganotin(IV) 5-[( E )-2-(4-methylphenyl)-1-diazenyl]-2-hydroxybenzoates, viz., (Me 3 Sn{O 2 CC 6 H 3 - p -OH[N N(C 6 H 4 -4-CH 3 )]}) n ( 1 ), Et 3 Sn{O 2 CC 6 H 3 - p -OH[N N(C 6 H 4 -4-CH 3 )]}OH 2 ( 2 ), and Bz 3 Sn{O 2 CC 6 H 3 - p -OH[N N(C 6 H 4 -4-CH 3 )]} ( 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 ( 1 H, 13 C, 119 Sn), and 119m Sn Mossbauer experiments.
