Abstract

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.

摘要

Tc(II)亚硝酰配合物(Bu(4)N)[Tc(NO)Cl(4)]与二-(2-吡啶甲基)(NEt)胺在甲醇中反应生成中性配合物[Tc(NO)Cl(py-N(Et)-py)]。Tc(I)亚硝酰配合物[Tc(NO)Cl(2)(HOMe)(PPh(3))(2)]与这种三齿配体反应生成阳离子型[Tc(NO)Cl(py-N(Et)-py)(PPh(3))]Cl。这两种配合物已通过结构表征。[Tc(NO)Cl(2)(HOMe)(PPh(3))(2)]与四齿配体1,4-双(2-吡啶甲基)-1,4-二氮杂丁烷反应生成包括阳离子型[Tc(NO)Cl(py-NH-NH-py)]Cl和阳离子型[Tc(NO)Cl(PPh(3))(py-NH-NH~py)]Cl在内的产物混合物，其中一个吡啶末端悬空。
