| Abstract: | Mössbauer effect experiments have been carried out on 60Co and reactor irradiated CFe(CO)3SCH1]2, (C4H9)2SnFe(CO)4]3, (C6H5)1PFe(CO)4, (CH2)4Fe(CO)2C3H5]2, and (CH2)4.(CO)2Fe(CO)2C5H5]2. It was found that the Fe—CO bond is rather radiation resistant than are expected due to the π bonding character. The σ bonds such as C—H are labile to radiation. The presence of acyl carbonyl group increase the radiation resistant property of the molecule. The increase in the isomer shift values of the complexes with cyclopentadienyl groups were interpreted as a result of dehydrogenation. |
