A series of iron(III) σ-bonded porphycenes are characterized by their electrochemical and spectroscopic properties. The investigated compounds are represented as (EtioPc)Fe(R), where EtioPc = the dianion of 2,7,12,17-tetraethyl-3,6,13,16-tetramethylporphycene and R = C6H5, 3,5-C6F2H3, 3,4,5-C6F3H2 or 2,3,5,6-C6F4H. Each compound is characterized as to its ESR, NMR, and UV−visible properties which are compared to corresponding compounds in an analogous series of (OEP)Fe(R) and (OETPP)Fe(R) derivatives where OEP and OETPP are the dianions of octaethyl- and octaethyltetraphenylporphyrin, respectively. The (EtioPc)Fe(R) complexes contain either high- or low-spin Fe(III), depending on the specif…

A series of high- and low-spin iron(III) phenyl and fluorophenyl octaethylporphyrin complexes are characterized by their electrochemical and spectroscopic properties in nonaqueous media. The investigated compounds are represented as (OEP)Fe(R), where R = C6H5, 3,4,5-C6F3H2, 2,4,6-C6F3H2, C6F4H, or C6F5 and OEP is the dianion of 2,3,7,8,12,13,17,18-octaethylporphyrin. The two C6F3H2 complexes are of special interest in that these isomers differ in the spin state of the iron(III). Electrochemical studies indicate that three one-electron oxidations are seen for all of the (OEP)Fe(R) derivatives which were investigated both at room and low temperature under conditions where migration of the σ-b…
