Abstract
Synthesis and properties of metalocene dithiolene chelates Cp2ML with metal(IV) ions (M) of group IVA (Ti, Zr, Hf) and of vanadium with L = dmit (1,3-dithiole-2-thione-4,5-dithiolate), dmt (1,2-dithiole-3-thion e-4,5-dithiolate), dmid (1,3-dithiole-2-one-4,5-dithiolate) and dmise (1,3-dithiole-2-selone-4,5-dithiolate) are described. The structures o f these compounds were discussed using IR-, UV/VIS-, H-1-NMR-, C-13-NM R- and EPR data. The activation parameters of the chelate ring inversi on of titanocene dithiolenes (Cp2TiL) and the x-ray structure of Cp2Ti (dmid) are given.
