1-crotonyl-2,4-diaza-1,3-butanedione Metal Complexes: Synthesis and Spectroscopic Investigations

Abstract

The iron(II), cobalt(II), nickel(II), copper(II) and zinc(II) complexes of l-crotonyl-2,4-diaza-l,3-bainedione (cru) have been prepared. They have been characterized by elemental analyses, conductance, room temperature magnetic susceptibility, infrared, electronic, ¹H and ¹³C NMR spectral data. Based on the analytical data, the stoichiometry of the complexes is 1:2. The conductivity shows that all of these complexes are non-electrolytes. The studies indicate that the geometry around the metal ion of the complexes is octahedral.
