%X The complexes formed by 4,4?-bipyridine with uranyl chloride, sulphate, and nitrate of the type UO2(4,4?-bipyridine)X2, where X = Cl or 1/2SO4, and UO2(4,4?-bi-pyridine)1.5(NO3)2 have been prepared and their infrared spectra in the rock salt and low-frequency region (down to 200 cm-1) studied in the solid state. I.r. spectra of these complexes show that 4,4?-bipyridine acts as a bidentate ligand bridging between two metal atoms. It is suggested that the sulphate and nitrate groups act as bidentate chelating ligands and the complexes are polymeric structures.
