Abstract

Esr studies of α,β, γ, δ -tetra(p-methoxyphenyl)porphinatocobalt.(II) in toluene glasses in the presence of various concentrations of a number of different amines show the formation of both five- and six-coordinate complexes. The esr parameters are quite insensitive to the basicity of the amine, and the resolution of the spectrum is determined by the composition of the glass. In the presence of air, the esr spectrum undergoes a dramatic change, attributed to the formation of a six-coordinate complex containing one amine and one oxygen molecule as the fifth and sixth ligands. © 1970, American Chemical Society.
