摘要：

The reaction of the Tc(II) nitrosyl complex (Bu4N)[Tc(NO)Cl-4] with di-(2-picolyl)(NEt)amine in methanol yields the neutral complex [Tc(NO) Cl(py-N(Et)-py)]. The reaction of the Tc(I) nitrosyl complex [Tc(NO)Cl-2(HOMe)(PPh3)(2)] with this tridentate ligand yields cationic [Tc(NO) Cl(py-N(Et)-py)(PPh3)] Cl. These two complexes have been structurally characterized. The reaction of [Tc(NO)Cl-2(HOMe)(PPh3)(2)] with the tetradentate ligand 1,4-bis-(2-pyridylmethyl)-1,4-diazobutane yields a mixture of products including cationic [Tc(NO)Cl(py-NH-NH-py)]Cl and cationic [Tc(NO)Cl(PPh3)(py-NH-NH similar to py)]Cl, with a pyridyl terminus left dangling.
