Thiolate ligands, sterically hindered structures

More recently three other mononuclear [Fe(SR)4]- complexes containing monodentate thiolate have been structurally defined. In these SR = SPh-,219 SEt-219 and 2,3,5,6-tetramethylben-zenethiolate.220 Sterically hindered thiolate ligands appear to stabilize the [Fe(SR)4] coordination unit and thus provide a means for the preparation by ligand exchange of the previously elusive (non-hindered) monodentate tetrathiolato iron(III) complexes. [Pg.235]

The homoleptic sterically hindered thiolate complex [Mo2(TMT)g] containing Mo— Mo triple bonds was first prepared by a multistep reaction (35). The X-ray crystal structure showed a staggered configuration for the thiolate ligands with an Mo— Mo distance of 2.228(1) A (35). They were synthesized subsequently by a simple one-step synthesis involving the reaction of M0CI4 with the TIPT anion in 1,2-dimeth-oxyethane and structurally characterized. A study of their chemistry showed them to be rather unreactive compared with their alkoxide analogues (36). [Pg.422]
