%0 Journal Article %T Spectroscopy and thermal studies of the reaction of iodine with cobalt (II) and copper (II) acetylacetonate %A Sadeek %A S.A. %J Anales de la Asociaci£¿3n Qu£¿-mica Argentina %D 2005 %I Scientific Electronic Library Online %X a spectrophotometric study of 1:1 charge-transfer complexes derived from two metal acetylacetonates ( co (ii) and cu (ii) acetylacetonates) donor and iodine ( s-acceptor ) has been carried out. the equilibrium constants ( k ) and absortivity ( e ) for the formation of the chelate-iodine complexes have been evaluated. the suggested structure of the two solid triiodide charge-transfer complexes reported in this study is further supported by thermal analysis and far and mid infrared measurements. %U http://www.scielo.org.ar/scielo.php?script=sci_abstract&pid=S0365-03752005000100019&lng=en&nrm=iso&tlng=en
