The compounds LTc(CO)3 (L C5Me5, C5Me4Et, Ind) were synthesized for the first time and their structures as well as the well-known (C5Me5)Re(CO)3 were determined by single-crystal X-ray diffraction. The IR, 1H NMR, 13C NMR and the UV spectra are reported and discussed.
首次合成了LTc(CO)3(L C 5 Me 5,C 5 Me 4 Et,Ind)化合物及其结构以及众所周知的(C 5 Me 5)Re(CO)3通过单晶X射线衍射确定。报道并讨论了IR,1 H NMR,13 C NMR和UV光谱。

The kinetics of the following reactions in decalinhave been studied : the complexes [MnRe(CO)10] and [Tc2(CO)10] with triphenylphosphine, [MnRe(CO)8(PPh3)2] and [Tc2(CO)8(PPh3)2] with carbon monoxide, and decomposition of [Tc2(CO)10] under oxygen. The results are consistent with initial reversible homolytic fission of the metal–metal bonds so that the activation enthalpies for the rate-limiting steps
