Popis:	New simple and mixed complexes of 1-(2-pyridylazo)-2-naphthol (PAN) and 1,10-phenanthroline (phen) or 2,2′-bipyridyl (bipy) with nickel(II) and zinc(II) were synthesized and characterized by elemental analyses, conductivity, infrared, electronic spectra, room temperature magnetic measurements, and X-ray diffraction studies. The I. R. data suggest the coordination of PAN through oxygen and (pyridine) nitrogen, whereas phen and bipy coordinate through the pyridine nitrogens. The UV-Vis. spectra along with magnetic measurements favor a tetrahedral geometry for the complexes. The podwer X-ray diffraction studies indicate tetragonal symmetry for all these complexes except for Ni(II)-PAN-phen, which has orthorhombic symmetry. aPresent address: School of Materials Science and Technology, I.
