摘要:
The iron trithiocarbonato complex CpFe(CO)(2)(kappa S-SCS2Ph) (1a) and its selenodithiocarbonato, analogue CpFe(CO)(2)(kappa Se-SeCS2Ph) (1b) were generated by room temperature reactions of (mu-E-x)[CpFe(CO)(2)](2) (E = S; x = 2, 3. E = Se; x = 1) with PhSC(S)Cl. These compounds can be converted into the complexes CpFe(Co)(kappa S-2,E-ECS2Ph) [E = S (2a), Se (2b)], in which the trithiocarbonato or the selenodithiocarbonato ligand is bonded to the iron in a chelate form, under photolytic conditions. The composition and structure of all products have been verified by elemental analyses, IR and H-1 NMR spectroscopies. The crystal structures for compounds la, 1b, and 2b show a three-legged piano-stool configuration at Fe in each complex. The spectroscopic and structural data in this work are commensurate with the electronic factor of the S- and Se-donor ligands. (c) 2007 Elsevier Ltd. All rights reserved.
