Abstract

The title compound, PHZ, can be viewed as 1,5-diazacyclooctane (daco) having carbon-3 and carbon-7 fused to benzene rings restricting the vibrational freedom of these carbons and rendering the axial positions in the complexes open for fifth and sixth coordination. Copper(II), nickel(H) and zinc(H) complexes of PHZ have been prepared. Copper(II) formed mono-and bis-complexes, whereas nickel(H) and zinc(II) formed only bis-complexes. The diamagnetic nickel(II) complexes are planar like the corresponding complexes of mesocyclic diamines, daco and dach. The copper(II) complexes differ appreciably from the mesocyclic diamine complexes of copper(II). Zinc (II) formed tetra-hedral complexes with two monodentate PHZ ligands and anions in the first coordination sphere. The structures of the complexes have been assigned by analysis of their spectral, magnetic and conductance data. The thermogravimetric studies of the complexes are also reported and discussed.
