Nicotinic acid complexes with uranyl salts
Description
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 only via its pyridine ring nitrogen in all cases. The uranyl chloride and sulphate complexes are monomeric hexacoordinated structures, while the nitrate and acetate complexes are octacoordinate around uranium. (orig.)
Abstract (German)
Der potentiell zweizaehnige Ligand Nikotinsaeure bildet mit Uranylchlorid, -sulfat, -nitrat und -acetat 2:1-Komplexe, die durch Messung mittels Infrarotspektroskopie bis herab zu 200 cm-1 im festen Zustand charakterisiert wurden. Die Ergebnisse lassen den Schluss zu, dass die Nikotinsaeure in allen Faellen nur ueber ihren Pyridinring = Stickstoff koordiniert. Die Uranylchlorid- und -sulfatkomplexe sind monomerische hexakoordinierte Strukturen, waehrend die Nitrat- und Acetatkomplexe oktaedrische Konfiguration um das Uran besitzen.
