Abstract
Pyridinecarboxylix acids contg. a carboxylic group in position 2 react with oxovanadium(IV) ions in aq. soln. giving sol. chelates. For values of -log[H+] <3.5, 1:1 and 1:2 metal to ligand mononuclear complexes were evidenced and their stability consts. were calcd. at 25° in 0.5 M NaClO4 by means of potentiometric measurements of H ion concn.File allegati a questo prodotto
