Thermomagnetic analysis of hemin and related compounds

Abstract

Some simple classical current loop calculations have been carried out on the phthalocyanine ring. Data for the calculations have been supplied by some single-ring and multi-ring silicon and germanium phthalocyanines. Possible structural uses are forseen for the results.

(12,17-Diethoxycarbonyl-2,3,6,7,11,18-hexamethylcorrphycenato-κ4N)iodoiron(III) chloroform solvate

“…Insertion of iron was carried out after Adler (Adler et al, 1970). The chloroiron(III) complex thus obtained was converted to the title complex by cleaving of the "-oxo-bridged dimers (Maricondi et al, 1969). The solid was recrystallized from chloroform solution.…”

The effect of heat treatment on group VIIIB porphyrins as electrocatalysts in the cathodic reduction of oxygen

“…Unheated ClTPPFeIII is known to be a high-spin d5-complex. 20 The value of peff determined using eqn (2) was 5 . 7 ~~ (Bohr magnetons), in good agreement with the value of 5.9pB given in the literature.20 This value was little changed by heat treatment up to 400 "C, but a pronounced increase occurred between 400 and 500 "C. A further change in peff was observed between 750 and 800 "C. These changes in peff for ClTPPFeIII correspond to the changes in the t.g.…”
