Studies on reactions of some ruthenium sulfoxide bipyridyl complexes with 1,4-bis(salicylidene)phenylenediamine ligand used as spacer

摘要

A dinucleating spacer 1,4-bis(salicylidene)phenylenediamine (SALPHEN) derived from 1,4-phenylenediamine and salicylaldehyde has been synthesized and characterized. The ruthenium(II) sulfoxide derivative of 2,2′-bipyridine or 1,10-phenanthroline on reaction with this ligand resulted in the formation of eight dinuclear complexes, which were characterized by elemental analyses, conductivity measurements, magnetic susceptibility, FT-IR, fast atom bombardment-mass spectra, electronic spectroscopy, 1H-NMR, 13C{1H}-NMR, and 2D-NMR spectra (HETCOR). The prepared complexes have two different formulations, [{trans-RuCl₂(so)(N-N′)}₂(μ-SALPHEN)] and [{cis-RuCl₂(so)(N-N′)}₂(μ-SALPHEN)], where so = dimethyl sulfoxide (DMSO)/tetramethylene sulfoxide (TMSO), N-N′ = 2,2′-bipyridine/1,10-phenanthroline, and SALPHEN = 1,4-bis(salicylidene)phenylenediamine. Two moles of ruthenium sulfoxide bipyridine precursor were coordinated to the bidentate SALPHEN through nitrogen. All the complexes possess antibacterial activity against Escherichia coli in comparison to Chloramphenicol.View full textDownload full textKeywordsPhenyldiamine, 1,4-Bis(salicylidene)phenylenediamine, Ruthenium sulfoxide, BipyridineRelated 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/10.1080/00958972.2012.657630
