Complexes of a new bidentate chelating pyridyl/sulfonamide ligand with copper(II), cobalt(II) and palladium(II): crystal structures and spectroscopic propertiesComplexes of a new bidentate chelating pyridyl/sulfonamide ligand with copper(II), cobalt(II) and palladium(II): crystal structures and spectroscopic properties Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-09-241998enReaction of the bidentate ligand 2-(2-aminophenyl)pyridine with p-toluenesulfonyl chloride afforded the new bidentate ligand HL which contains potentially chelating pyridyl and (protonated) sulfonamide N-donor binding sites. The crystal structure of the ligand shows that the sulfonamide NH proton is involved in a hydrogen-bonding interaction with the pyridyl N atom, resulting in a near-coplanar arrangement of the pyridyl and phenyl rings.http://creativecommons.org/licenses/by/4.0/Inorganica chimica acta2782178-184 Elefteria Psillakis Carl A Otter Samantha M Couchman John C Jeffery Karen LV Mann Michael D Ward Elsevier
