摘要：

The known complex, [(ReO3(HB(pz)3)], where [HB(pz)3]- is hydrotris(1-pyrazolyl)borate, has been prepared by three new methods: (i) the nitric acid oxidation of [ReOCl2(HB(pz)3)]; (ii) the thermolysis of [ReO(eg)(HB(pz)3)], where eg is ethylene glycolate; (iii) the reaction of [NH4(ReO4)] and [HB(pz)3]- in acidified methanol. The technetium analogue, [TcO3(HB(pz)3)], has also been synthesized here by two methods; (i) the nitric acid oxidation of [TcOCl2(HB(pz)3)]; (ii) the reaction of [TcO4]- and [HB(pz)3]- in acidified ethanol. Both complexes have been characterized by elemental analyses, mass spectrometry, and IR and NMR spectroscopies. The reaction of [TcO3(HB(pz)3)] with ethylene to form [TcO(eg)(HB(pz)3)] is also discussed.
