    • Abstract


      The non-electrolytic compounds of composition MCln(ONp)5-n have been prepared by digesting the niobium pentachloride with β-naphthol in an appropriate molar ratio in carbon tetrachloride. The hexa-, hepta- and octa-coordinated derivatives of Nb(V) have been isolated by reacting Nb (ONp)5 with N,N’-diarylformamidino-N“-arylcarbamides, thiocarbamides and N-benzoylformamidino-N’-arylcarbamides and thiocarbamides, of the general formula Nb (ONp)4(L); Nb (ONp)3(L)2 and Nb (ONp)2(L)3; (L= a molecule of bidentate ligand).
