Abstract
Oxidation of the planar four-coordinate complex Ni(C18H14N4) with halogens (bromine and iodine) results in the formation of new complexes of Ni(C18H14N4)I1.57 and Ni(C18H14N4)Br2.43 stoichiometry. They all form semiconducting solids with specific conductivity 4.4 × 10-3 ohm-1cm-1 for Ni(C18H14N4)I1.57 and 1.3 × 10-5 ohm-1cm-1 for Ni(C18H14N4)Br2.43). These compounds were characterized by elemental analyses and spectroscopic means; resonance Raman studies on Ni(C18H14N4)I1.57 indicate that iodine is present as I3-; EPR studies show an essentially ligand based character of the odd electron, thus the conductive path of these materials may involve π-π and perhaps d-π overlap. © 1980.
