Syntheses and characterizations of di- and tri-organotin carboxylates of 4-oxo-4-phenyl butanoic and 4-(4-biphenyl)-4-oxobutyric acid

摘要

A family of organotin carboxylates, [(C₆H₅)₃Sn(L1)₂] (1) and [(C₆H₁₁)₂Sn(L2)] (2), was synthesized from reaction of R₃SnOH and (where R = phenyl, R′ = cyclohexyl) with 4-oxo-4-phenyl butanoic (L1H) and 4-(4-biphenyl)-4-oxobutyric acid (L2H) in suitable mole ratios. They have been characterized by elemental analysis, FT-IR, 1H NMR spectroscopy, and single-crystal X-ray diffraction analysis. In 1, the geometry of tin is trigonal bipyramidal. Supramolecular architecture of 1 shows a polymeric chain structure with Ph₃Sn centers linked by PhCOC₂H₄CO₂ ligands via O → Sn interactions. Sn···Sn non-bonded distances in the repeating 1-D polymeric structure equal 5.835 à . Complex 2 contains an angular sector and adopts a distorted tetrahedral geometry.View full textDownload full textKeywordsOrganotin carboxylate, 4-Oxo-4-phenyl butanoic, 4-(4-Biphenyl)-4-oxobutyric acid, Synthesis, Crystal structureRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/00958972.2012.724680
