The complexation properties of some coumarin derivatives toward alkali metal, alkaline earth metal, some transition metal and some heavy metal cations have been investigated in acetonitrile by means of UV spectrophotometry absorption and conductivity. Thus, the stoichiometries of complexes formed and their stability constants were determined by digital processing of data.
