چکیده
The reaction of the Tc(II) nitrosyl complex (Bu(4)N)[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)(PPh(3))(2)] with this tridentate ligand yields cationic [Tc(NO)Cl(py-N(Et)-py)(PPh(3))]Cl. These two complexes have been structurally characterized. The reaction of [Tc(NO)Cl(2)(HOMe)(PPh(3))(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(PPh(3))(py-NH-NH~py)]Cl, with a pyridyl terminus left dangling.
