title = "Complexation of tricarbonyltechnetium(I) ion with halide and thiocyanate ions in aqueous solution: 99Tc NMR study",

abstract = "Complexation of the Tc(CO)3(H2O)3 + ion with halide (F-, Cl-, Br-, I-) and thiocyanate ions in aqueous solutions was studied by 99Tc NMR spectroscopy. The stability constants of the mono-, di-, and tri-substituted complexes were calculated. The stability of halide (Cl -, Br-, I-) complexes grows as the ionic radius of the halogen increases and its electronegativity decreases. For halide complexes of similar composition, the 99Tc chemical shift correlates with the stability of the complexes. The fluoride ion, most probably, does not coordinate with the Tc(CO)3+ ion, in contrast to its close analog, hydroxide ion. Among the ligands studied, the pseudohalide anion NCS- forms the most stable complexes with the Tc(CO)3 + ion.",
