摘要：
Pyrolytic transformation of the complex Cp2Mo2(CO)4(dmad) (Cp = cyclopentadienyl, dmad = dimethylacetylenedicarboxylate) under hydrogen at 550-degrees-C gives, after a passivation step, Mo2C with an excess of carbon and oxygen. These impurities can be withdrawn with an appropriate reductive post-treatment. Based on thermogravimetric analyses and pyrolysis mass spectroscopy performed on the precursor, a preliminary decomposition scheme has been proposed.
