1. Direct incorporation of a ferric ion in the porphyrinogen core: Tetrakis(cyclohexyl)iron porphyrinogen anion with different conformers and its reaction with iodine

Abstract

Et(sub 4)N[L'Fe(super III)]-3DCM is directly synthesized by adding ferric chloride into a solution of a lithium salt of tetrakis(cyclohexyl)-porphyrinogen (L'). Et(sub 4)N[L'Fe(super III)]-3DCM showed polymorphism, and with pyridine in the lattice, it changed to Et(sub 4)N-[L'Fe(super III)]-DCM(sub 0.5)Py(sub 1.5), possessing two different conformers.

Abstract

Tetraethylammonium-tetrakis(cyclohexyl)porphyrinogenCu(II) is oxidized by aerial oxygen to the corresponding Cu(III) species, thus producing tetraethylammonium-tetrakis(cyclohexyl)porphyrinogenCu(II) equiv of [O.sub.2.sup.-]. Steric crowding of the peripheral hydrogens in tetraethylammonium-tetrakis(cyclohexyl)porphyrinogenCu(II) has prevented any direct Cu-[O.sub.2] bond formation in the oxidation process, which has shown an outer-sphere electron transfer reaction.

Abstract

The meso-tetrakis(3,4,5-trimethoxyphenyl)cobalt(II) porphyrin [Co(TMPP)] is synthesized by a new method. The X-ray structure of meso-tetrakis(3,4,5-trimethoxyphenyl)cobalt(II) porphyrin [Co(TMPP)] grown in dichloromethane shows square-pyramidal coordination around the Co(II) ion, showing a 1D polymeric network while it displays an octahedral coordination around Co(II), when grown in chloroform, resulting in a 2D coordination network.
