✦ Synopsis

A novel unsymmetrical tetradentate azine, 2-acetylpyridinesalicylaldazine (Haps), was prepared by condensing salicylhydrazone with 2-acetylpyridine, and was characterized by elemental analysis and its i.r. spectrum. This ligand reacted with Mn, Co, Ni, Cu and Zn acetates to yield deprotonated M(aps)2(H20)2 complexes. Subsequent reaction of the mononuclear unit Zn(aps)2(H20)2 with MC12 gave homo-[ZnC12Zn(aps)2(H20)2 ] and heterobinuclear [MC12Zn(aps)2(H20)2] type azine-bridged complexes, which were characterized by analytical, molecular weight, conductivity (solid and solution), magnetic susceptibility, and electronic, e.s.r, and i.r. spectroscopies, and X-ray powder diffraction data.
