The solution chemistry and interactions of niobocene dichloride, Cp2NbCl2, with nucleosides, nucleotides, and amino acids has been studied by 1H and 31P NMR spectroscopy. The 1H NMR spectrum of Cp2NbCl2 in 10% DMSO-d6/D2O contains two sharp singlets consistent with hydrolysis

The interaction of the antitumor active metallocene dihalides Cp(2)MCl(2) (M=Ti, Nb, Mo) and 1 equiv. of glutathione was studied by (1)H NMR spectroscopy at pD 2-7 in 4 mM NaCl solutions. No interaction between glutathione and titanocene dichloride was detected
