Reaction of intrasphere transformation of acetonitrile in niobium pentachloride complexes with triethylamine, tributyl- and triphenylphosphine

Experimental data on the study of reaction of intrasphere transformation of acetonitrile in niobiUm pentachloride complexes with triethslamine, tributyl- and triphenylphosphine using the spectral methods of investigation are discUssed. It is shown that intrasphere transformation of acetonitrile, accompanied by its deprotonation, is common for all reactions of introduction into NbCl5 complexes with donor ligands N(C2H5)3, (C4H9)3P, (C6H5)3P. A previously made conclusion that the reactions of nitrile introduction into complexes of tantalum and niobium pentachlorides promote mutuat effect; of molecular and acidoligands in the inner sphere of the complex is confirmed
