Studies on the Formation and Composition of Copper(II)-α- and γ-Halo-1-Oxobutanilides Complexes: Figure 1

Figure 1: The ultraviolet absorption spectra of copper acetate. (a) γ-Br-A.A.A., and their complexes formed by the continuous variation method. (b) (Cu): 8×10⁻⁵ M, Br-A.A.A.: 9×10⁻⁵ M, and complexes of copper: ligand in ratios (1 = 9:1, 2 = 8:2, 3 = 7:3, 4 = 6:4, 5 = 5:5, 6 = 4:6, 7 = 3:7, 8 = 2:8, and 9 = 1:9).
