CARBON-13 NUCLEAR MAGNETIC RESONANCE OF METAL COMPLEXES. I.

Abstract
Carbon-13 chemical shifts were measured for 15 cyanometallate complexes in aqueous solution with Fourier-Transform NMR spectroscopy. The chemical shift values are distributed between −50.33 ppm (from external benzene standard) for Fe(CN)64− and +2.66 ppm for Pt(CN)42−. The coupling constant 1JC-Co was found to be 126 ± 4 Hz for Co(CN)63−.
