σ-η2 Transformation of an electron-rich thioarsenic heterocyclic ligand: X-ray crystal structure of [Mo(η2-AsSCH2CH2S)(CO)2(η-C5H5)]
Abstract
Photolysis of the complex [Mo(σ-[graphic omitted])(CO)3(η-C5H5)] causes elimination of carbon monoxide and formation of [Mo(η2-[graphic omitted])(CO)2(η-C5H5)] in which the ring behaves as a di-hapto, formally three-electron donor.
