SYNTHESIS AND INFRARED STUDY OF SOME PHENYLPHOSPHONATE, DIPHENYLPHOSPHINATE AND ACETATOPHOSPHONATE NEW ORGANOTIN (IV) DERIVATIVES AND ADDUCTS

Abstract

Three organotin (IV) derivatives PhPO₃HSnBu₂Cl, SnBu₂Ph₂PO₂Cl×3/2H₂O, Sn(PhPO₃)Cl₂×2H₂O obtained on allowing PhPO₃H₂ or propylammonium PhPO₃H to react with SnBu₂Cl₂, SnCl₂×2H₂O and two adducts [(C₆H₅CH₂)₂NH₂]₃O₂C(CH₂)₂PO₃×3SnPh₃Cl, [CyNH₃(HO₂POCH₂-N(CH₂CO₂H)₂]₂×3SnCl₄.2H₂O×NH₄Cl obtained on allowing (C₆H₅CH₂)NH₂)₃O₂C(CH₂)₂PO₃ or [CyNH₃(HO₂POCH₂-N(CH₂ CO₂H)₂]₂ and SnPh₃Cl or SnCl₂×2H₂O to react in ethanolic media have been characterized by elemental analyses, infrared and Mossbauer techniques. The suggested structures, while considering the anionic counterpart, are discrete, dimeric, double and triple metallic components or of infinite chain types, the anion behaving as a monochelating, a bichelating or a bidentate ligand. In OH containing structures, when extra hydrogen bonds are considered, supramolecular architectures may be obtained.
