Jackels, Susan C. published the artcileTetragonal cobalt(III) complexes containing tetradentate macrocyclic amine ligands with different degrees of unsaturation, Safety of Propane-1,3-diamine dihydrochloride, the publication is Inorganic Chemistry (1972), 11(12), 2893-901, database is CAplus.
The syntheses, structures, and properties of trans-[Co(TIM)X2]Z, trans-[Co(DIM)X2]Z and trans-Co(DMC)X2]Z (TIM = I; DIM = II; DMC = III; X halide or NO2; Z = halide, ClO4-, or PF6-) were reported. Infrared and PMR spectral studies provided proof of the structures of the macrocyclic ligands in these compounds and the latter gave insight into stereochem. relations among these complexes. Spectrochem. studies revealed that the ligand field strengths of the macro-cycles increased as the degree of unsaturation of the ligand increases. Comparisons with other macrocycles showed the relative effect on ligand field strengths of such groups as -N(H)-, N:c, -N:C-C:N-, and pyridine. Voltammetric data showed that the lower oxidation states of Co are stabilized by greater degrees of ligand unsaturation
