From aqueous solutions containing niobium(V), sulphuric acid and an excess of thiocyanate, under the conditions for the spectrophotometricdetermination of niobium, the compounds [(C6H5)4P]2 [NbO(NCS)s], [(C6Hs)4As]2 [NbO(NCS)s] and [(C2Hs)4N]2 [NbO(NCS)5) were isolated either by crystallization or by extraction with diethyl ether and evaporation o·f the extracts. (C2H2N2S3)2H[Nb(NCS)a] was isolated from an ether extract only. The compounds have been characterised by analytical data, .infrared spectra, magnetic and conductivti.ty measurements. In all the compounds the thiocyanate groups bond through the nitrogen atom
