Studies on transition-metal cyano-complexes. Part 3. Heptacyano-complexes of tungsten, molybdenum, and vanadium, and a hydrido-heptacyano-complex of tungsten
Abstract
The new complexes K5[W(CN)7]·H2O and K4[WH(CN)7]·2H2O are reported, and have been characterised by 1H, 13C n.m.r., and vibrational spectra. Vibrational and e.s.r. data are also presented for the new salt NaK3[Mo(CN)7]·2H2O and earlier data are extended for K4[Mo(CN)7]·2H2O and K4[V(CN)7]·2H2O.
