Actinide porphyrin complexes
The first bis(porphyrin)actinide complexes have been prepared by reaction of M(NEt$\sb2$)$\sb4$ (where M = Th, U) with H$\sb2$TPP or H$\sb2$OEP. The coordination geometry of (TPP)$\sb2$Th is a distorted square-prism where the thorium center is displaced 1.47 A from each of the porphyrin N$\sb4$ …

Synthetic Iron Porphyrins as Models for Heme Proteins
Various iron porphyrin complexes have been studied as models for the active sites of heme proteins. Spectroscopic studies of (FeTPP)(,2)N('+) (where TPP is the dianion of tetraphenylporphyrin) and (FeTPP)(,2)C indicate that these complexes contain iron(IV). This behavior can be contrasted with the …
