Drum-shaped mono-organooxotin assembly through solvothermal synthesis with 2,3,4,5-tetrafluorobenzoic acid: crystal structure, hydrogen bonding and π-π stacking interactions

摘要

A drum-shaped organooxotin (IV) complex with 2,3,4,5-tetrafluorobenzoic acid of the type {[SnR₂(2,3,4,5-F₄C₆HCO₂)]O}₆ (R = m-Cl-PhCH₂) has been solvothermally synthesized and structurally characterized by elemental, IR, 1H, 13C, 119Sn NMR spectra and X-ray crystallography diffraction analysis. This complex exhibits a new structural environment appearing as a “drum” arrangement with hexa-coordinated tin atoms in a four-membered stannoxane ring, (-Sn-O-)₂, as a common structural feature. Each tin(IV) displays a distorted octahedral geometry. Weak, but significant, intramolecular C-H ··· F hydrogen bonds and π-π stacking interactions are shown. These contacts lead to aggregation and supramolecular self-assembly. Cleavage of Sn-C bond occurred in complexes under the influence of strong acid.View full textDownload full textKeywords2,3,4,5-tetrafluorobenzoic acid, Organooxotin, Solvothermal synthesis, Assembly, Hydrogen bonding, π-π stacking interactionRelated 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/10.1080/00958970701324002
