Coordination Polymers of Some Uranyl Salts Involving 4,4' -Bipyrideyl, 4,4' -Bipyridyl N,N' -dioxide, 1,3-Bis(4-pyridyl) propane and Hexamethylenetetramine

Abstract

Analytical data and infrared spectral measurements down to 200 cm^–1 on the coordination compounds formed by the interaction of uranyl chloride, thiocyanate, nitrate, sulphate and acetate with 4,4´-bipyridyl, 4,4´-bipyridyl N,N´-dioxide, 1,3-bis (4-pyridyl) propane and hexamethylenetetramine indicate that the complexes are coordination polymers having four or six coordination around the uranyl UO₂²⁺ ion with bidentate bridging organic ligand molecules and terminally bonded chloro and thiocyanato groups and bidentate chelating nitrato, sulphato and acetato groups in the solid state.
