Tc—N, bond distance

The oxo moiety in these complexes exerts a strong trans effect in both the structural and kinetic senses. In the case of dichloro[hydrotris(l-pyrazolyl)borato]oxotech-netate(V)93 hexacoordination is forced by the chelating ligand however, the three pyrazole nitrogens are not equivalent. The Tc-N bond distances are 2.086 A, 2.088 A and 2.259 A, with the latter distance belonging to the nitrogen trans to the oxygen. [Pg.63]

The reaction of (NH4)SCN in aqueous solution with (NH4)2TcX 6 (X = Cl or Br) yields [Tc(NCS)6]2- together with the analogous Tc(III) complex131. The Tc(III) ion is octahedral with Tc-N bond distances averaging 2.045 A. Electrochemical studies in acetonitrile reveal a reversible one-electron transfer between the two oxidation states, so that solutions of [Tc(NCS)6]3 in air are quickly oxidized to the Tc(IV) form. [Pg.68]
