Reactions of uranium tetrachloride, uranyl nitrate and thorium nitrate with pyrazine (Pyz), pyrazine 2-carboxamide (Pyza) and pyrazine 2, 3-dicarboxamide (Pyzda) have been carried out to study their coordination behaviour. Structural aspects of the complexes formed are discussed from the results of molar conductance and infrared spectral studies.
