The complexation reaction between 2,3-dimethyl-1,2-dihydro-8H-pyrazolo[5,1-a]isoindol-
8-one, ligand and Ag+, Co2+, Hg2+, Zn2+, Ni2+, Cu2+, Cd2+, Mg2+, Cr3+, Fe3+ and Pb2+ ions
were studied conductometrically in acetonitrile solution. The formation constants of the 1:1
and 2:1 complexes (metal to ligand) were calculated from the computer fitting of the molar
conductance in various mole ratios at 15, 25, 35 and 45 0C. The enthalpy and entropy changes
of the complexation reactions in acetonitrile were estimated at four different temperatures.
