The proportion of ionic species of (-aminobutenoic acid was varied by changing the pH of background electrolyte. The stability constants of ML and ML2 complexes of Be(II) - (-aminobutenoic and Co(II) - (-aminobutenoic acid complexes were found to be (7.19 ± 0.09, 5.91 ± 0.11) and (4.19 ± 0.03, 3.57 ± 0.07) (logarithm stability constant values), respectively at ionic strength 0.1 Mol L-1 and a temperature of 35° C.
