摘要：
The reaction of the Tc(I) complex [Tc(NO)Cl-2(HOMe)(PPh3)(2)] with stoichiometric amounts of 2-mercatopyridine and a proton scavenger yields [Tc(NO)Cl(Spy)(PPh3)(2)] or [Tc(NO)(Spy)(2)(PPh3)], depending upon quantities of ligands employed. These two complexes have been structurally characterized. The small bite angles of the bidentate mercaptopyridine ligands cause significant deviation from octahedral coordination geometry.
