NMR, CD and MCD studies of vanadate-nucleoside complexes

Complex formation between tetraoxovanadate (V) and each of the nucleosides adenosine, guanosine, cytidine and uridine has been studied in a constant salt medium at pH 7. 13 C- and 51 V NMR studies show that only complexes with the formula V 2 L 2 (V=vanadate, L=nucleoside) are formed, and their formation constants have been determined
