In six kinds of mixed ligand acetylacetonatocobalt(III) complexes ((NH3)4-, (en)2-, α-trien-, β-trien-, fac(N)-i-dtma-, and mer(N)-i-dtma-complexes), the methine hydrogen of the coordinated acetylacetonate ion has been substituted with chlorine, bromine, and iodine, and in five of them excepting the mer(N)-i-dtma complex, it has been substituted with a nitro group. The halogenated and the nitrated complexes were isolated and identified by means of electronic absorption spectra and NMR spectra. The effects of the substitutions on the properties and the characteristics of the substitution reactions are described and discussed.
