Conclusions

  1. 1.

    On reaction of organometallic radicals M (C5H5)(CO)X (Fe, Mo, W) with ortho-quinones, the free radicals of the phenoxyl type formed initially as a result of cleavage of the CO groups are converted to metal-centered free radicals.

  2. 2.

    For molybdenum and tungsten, we found two types of complexes containing one and two ortho-quinone liganda.

  3. 3.

    The state of the Mo and W atoms is characterized by 4d1 and 5d1 electronic configurations with localization of the unpaired electron in the dxy orbital.

  4. 4.

    In order to describe the state of the Fe atom, we assume the configuration 3d7 with coordination by the unreduced form of the ortho-quinone.
