Preparation and Conductivity of Benzophenone-Iodine-Alkali Iodide Crystals Grown from Methanol

Polyiodide complexes of benzophenone (B) with iodine (I) and alkali iodide (MI, M = Na, K, Rb or Cs) have been prepared from methanol for the first time. The crystals of these complexes (abbreviated BIMI) are in the shape of hexagonal prisms with golden luster sides and black cross sections. BIMI complexes exhibit semiconductive behavior from 250 to 310 K with activation energies of 0.6 to 0.8 eV. Under an applied dc field at room temperature, the longitudinal conductivity of BIMI crystals is in the order of 10^?6 Scm^?1 and does not decrease over a period of half an hour, indicating no ionic conductivity in these complexes. In contrast, significant ionic conductivity is observed for benzophenone complexes grown from chloroform. It is concluded that the solvent molecules play an important role in determining the electrical behavior of the resulting benzophenone complexes. The results of conductivity and resonance Raman spectroscopic studies on the entire methanol series of BIMI complexes suggest that a common conduction pathway is probably provided by the polyiodide chains in this new series of benzophenone complexes.

Prepared and characterization of new macrocyclic Schiff bases and their binuclear copper complexes

The new five macrocyclic ligands were synthesized by reaction of 2,6-diaminopyridine and various dialdehydes. Then, their copper(II) perchlorate complexes were synthesized by template effect by reaction of 2,6-diaminopyridine, Cu(ClO(4))(2).6H(2)O and aldehydes. The ligands and their complexes have been characterized by elemental analysis, IR, (1)H and (13)C NMR, UV-vis spectra, magnetic susceptibility, conductivity measurements, mass spectra. All complexes are diamagnetic and binuclear. The diamagnetic behaviour of the binuclear complexes may be explained by a very strong anti-ferromagnetic interaction in the Cu-Cu pair.
