1-CROTONYL-2,4-DIAZA- 1 3-BUTANEDIONE METAL COMPLEXES: SYNTHESIS AND SPECTROSCOPIC INVESTIGATIONS

摘要

The iron(II), cobalt(II), nickel(II),copper(II) and zinc(II) complexes of 1-crotonyl-2,4-diaza-1,3-butanedione(cru) have been prepared.They have been characterized by elemental analyses,conductance, room temperature magnetic susceptibility,infrared, electronic, ~1H and ~3C NMR spectral data.Based on the analytical data, the stoichiometry of thecomplexes is 1:2. The conductivity shows that all ofthese complexes are non-electrolytes. The studiesindicate that the geometry around the metal ion of the complexes is octahedral.
