Based on acetylacetone a new organic reagent was synthesized. Its crystal structure was studied. Its complexation with copper was Studied by spectrophotometric method. The effect of the third component on the complexation of Cu–R was considered. The composition of the reactants was studied by different physico-chemical methods. The effect of foreign ions on complexation was studied. The technique was applied to the determination of trace amounts of copper in natural objects.
