摘要：

The stability constants of the copper(I) pi-complexes with the different acidic forms of fumaric and maleic acids (H2L, HL- and L2-) were derived as (0.23, 1.2 and 2.8) X 10(4) M-1 (maleic acid) and (0.73, 1.1 and 1.5) X 10(4) M-1 (fumaric acid), respectively, by either electrochemical or pulse radiolytic techniques. The influence of electron-donating/withdrawing substituents on the pi-ligands are discussed.
