Abstract
The following complexes of the chelating ligands 2-methyl-6-aminomethylpyridine (6-methyl-2-picolylamine or mepic) and 2-thioamidopyridine (thiopic) have been prepared and studied: [Cu mepic2X]X, where X = Cl, Br, I, NO3, ClO4, [Cu mepic2C2O4], [Ni mepic3][ClO4]2, [M(II) thiopic3][ClO4]2, [M(III) thiopic3][ClO4]3, (M(II) = Co, Ni; M(III) = CO, Fe), and [Co thiopic3]Cl2. Conductance measurements in ethanol, nitromethane, and nitrobenzene indicate that the [Cu mepic2X]X complexes are 5-covalent whilst the other complexes studied are 6-covalent. All the complexes are "spin free" excepting those of Co(III). Absorption spectra of the copper complexes in the near ultraviolet region were also made.Keywords
