Abstract

The protonation and zinc and silver ion coordination equilibria of 15 pyrido[1,2-a]pyrimidine derivatives were studied by polarographic, potentiometric and spectrophotometric methods. The compositions of the complexes and the corresponding stability constants were determined by computer evaluation of the data. The results reflected the effects of the configuration and the degree of saturation of the ring system of the ligand, the basicities of the donor atoms, chelate formation and the presence of substituents at different positions on the stabilities of the complexes.
