Summary
The potentially bidentate ligand, nicotinic acid, forms 2 : 1 complexes with uranyl chloride, sulphate, nitrate and acetate which have been characterized by i.r. spectral measurements down to 200 cm−1 in the solid state. These studies indicate conclusively that nicotinic acid coordinates onlyvia its pyridine ring nitrogen in all cases. The uranyl chloride arid sulphate complexes are monomeric hexacoordinated structures, while the nitrate and acetate complexes are octacoordinate around uranium.
