Abstract
2-Amino cyclopentene-1-dithiocarboxylic acid (ACDA) reduces Cu(II) and Rh(III) to form univalent complexes of composition Cu(ACDA), 2 H2O and Rh(ACDA) 2 H2O, the oxidised species being a dimer of ACDA. The Cu(I) may be obtained in higher yield by reacting cuprous iodide with ammonium salt of ACDA. A compound of composition Rh(ACDA) (PPh3) (H2O) is obtained by reacting ACDA with Rh(PPh3)3Cl. With Hg(II) a normal bis complex is formed. The compounds have been characterized by their infrared and electronic spectra, magnetic moment measurement and thermal analysis. In the complexes bonding occur through NH2 and deprotonated thiol group. A tentative mechanism for the formation of reduced metal complexes has been suggested.Keywords
