PHYSICOCHEMICAL STUDIES OF SOME MERCURY PYRIMIDINE COMPLEXES

Mercury(II) complexes of some pyrimidine derivatives were prepared and characterized by elemental analysis and spectral measurements. The H- 1 n.m.r and i.r. spectra show the ligands to be in the keto form. Ther mal analysis and electrical conductivity measurements of the complexes were investigated in the temperature range 30-250-degrees-C. The resu lts indicate slight semiconducting behaviour. The disparity in the act ivation energy values, DELTAE as calculated from the slopes of the lin ear parts of the electrical conductivity curves is due to the differen ce in the concentration of the imperfections contained in the differen t types of the complexes.
