Popis:	The synthesis and characterization of cobalt(II), nickel(II), copper(II), zinc(II) cadmium(II), mercury(II) and U(VI)O2 complexes containing salicylaldehyde cyanoacetylhydrazone (SCH), 1-salicyl-hydrazo-3-imino-3-isopropoxy propionic acid hydrazide (SIPPH) and 1-salicylhydrazo-3-imino-3-tert-butoxy propionic acid hydrazide (SIBPH) are reported. The metal complexes have been characterized on the basis of elemental analyses, spectra (NMR, IR, visible), molar conductivities and magnetic moments measurements. Infrared spectral data show that the ligands (SCH, SIPPH and SIBPH) behave in a tridentate and/or bidentate manner with different modes of coordination toward the metal ions. The stereochemistry of the Co(II), Ni(II) and Cu(II) complexes has also been discussed. Moreover, a polymeric structure via an imido group (C[dbnd]NH) for some Cu(II) complexes is considered. Finally NMR spectra of the ligands and some diamagnetic complexes are discussed.
