Almost colourless complexes of the type [MnpicCl2], [Mnpic2X2], [Mnpic3]I2 and [Mnpic3][ClO4]2, as well as the brown complexes [Fepic3]Br2 and [Fepic3]I2 have been prepared and studied ; pic being the chelating ligand 2-picolylamine (2-aminomethyl-pyridine) and X the halogen. Conductance and absorption spectroscopy in the near-ultraviolet region measurements, using nitromethane as solvent, indicate that all complexes investigated have a 6-coordinate structure, excepting the chloride [MnpicCl2], the structure of which is uncertain. The latter substance could be tetrahedral or octahedral by polymerization. This substance as well as the bischelate complexes behave as non-electrolytes in nitromethane, although they are ionized to bi-univalent electrolytes in methanol. The complexes containing three molecules of ligand to metal atom are bi-univalent electrolytes in both solvents. Measurements of magnetic susceptibility show that both the iron and manganese complexes have spin-free metal atoms.
