Spectroscopic studies on charge-transfer complexes formed in the reaction of ferric(III) acetylacetonate with σ- and π-acceptors
The reaction of ferric(III) acetylacetonate (donor), Fe(acac) 3, with iodine as a σ-acceptor and with other different π-acceptors have been studied spectrophotometrically at room temperature in chloroform. The π-acceptors used in this investigation are 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ)...

p-chloranil and 7,7′,8,8′-tetracyanoquinodimethane (TCNQ). The results indicate the formation of 1:1 charge-transfer complexes with a general formula, [Fe(acac)
