摘要

在由[99Tc(hfa)(CO)4] （hfa为1,1,1,5,5,5-六氟乙酰丙酮）、三苯基膦（PPh3）或吡啶（py）与CCl4组成的体系中，在长时间的相互作用过程中，hfa阴离子逐渐被氯离子取代，形成络合物fac-和mer-[99TcCl(CO)3(PPh3)2]和fac-[99TcCl(CO)3(py)2]。测定了配合物的晶体结构和分子结构。络合物[99TcCl(CO)3(PPh3)2]是第一个在结构上得到证实的三羰基二（三苯基膦）锝络合物的表面结构。

Reaction of Technetium(I) Tricarbonyl Hexafluoroacetylacetonate Complexes with CCl4: Formation and Crystal Structure of [99TcCl(CO)3(PPh3)2] Stereoisomers and of fac-[99TcCl(CO)3(C5H5N)2]

In the course of prolonged interaction in the system consisting of [⁹⁹Tc(hfa)(CO)₄] (hfa is the anion of 1,1,1,5,5,5-hexafluoroacetylacetone), triphenylphosphine (PPh₃) or pyridine (py), and CCl₄, the hfa anion is gradually displaced by the chloride ion with the formation of the complexes fac- and mer-[⁹⁹TcCl(CO)₃(PPh₃)₂] and fac-[⁹⁹TcCl(CO)₃(py)₂]. The crystal and molecular structures of the complexes were determined. The complex fac-[⁹⁹TcCl(CO)₃(PPh₃)₂] is the first structurally confirmed example of technetium(I) tricarbonyl bis(triphenylphosphine) complexes of facial structure.
