Abstract
The stability constants of the copper(I) pi-complexes with the differe nt acidic forms of fumaric and maleic acids (H2L, HL- and L2-) were de rived 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 electroch emical or pulse radiolytic techniques. The influence of electron-donat ing/withdrawing substituents on the pi-ligands are discussed.
