The rate constant of ligand exchange on the complex fac ‐[ 99 Tc(H 2 O) 3 (CO) 3 ] + was determined by means of 13 C, 17 O, and 99 Tc NMR spectroscopy under pressurized conditions in aqueous media. After keeping the sample under CO pressure for an extended period, the formation of [ 99 Tc(CO) 6 ] + could unambiguously be detected in the 13 C and 99 Tc NMR spectra.
