- Abstract
The diorganotin(IV) complexes of methyl 2-{4-hydroxy-3-[(2-hydroxy-phenylimino)-methyl]-phenylazo}-benzoate (H2L) were obtained by the reaction of ortho-aminophenol, R2SnO (R = Me, nBu, or Ph) and methyl 2-[(E)-(3-formyl-4-hydroxy)diazenyl]benzoate (H2PL2) in ethanol, which led to diorganotin(IV) compounds of composition [Me2SnL]2 ( 1), nBu2SnL ( 2), and Ph2SnL ( 3) in good yield. The 1H, 13C, and 119Sn NMR, IR, the mass spectrometry along with elemental analyses allowed establishing the structure of ligand (H2L) and compounds 1-3. In all the three cases, 119Sn chemical shifts are indicators of five-coordinated Sn atoms in a solution state. The crystal structures of ligand H2L and complexes 1 and 2 were determined by a single crystal X-ray diffraction study. In the solid state, the ligand H2L exists as a keto-enamine tautomeric form. The molecular structure of complex 1 in the solid state shows a distorted octahedral geometry around a tin atom due to additional coordination with an oxygen atom from a neighboring molecule leading to a four-membered ring with Sn-O···Sn-O intermolecular coordination, leading to a dimeric species. On the other hand, complex 2 is a monomer with trigonal bipyramidal geometry surrounding the tin atom. © 2012 Wiley Periodicals, Inc.
