Abstract
The monocyclooctatetraene uranium bis(thiolate) complexes [U(cot)(SR)2 ] (cot = eta-C8H8, R = Bu(n) or Pr(i)) were prepared by treating [U(co t)(BH4)2] 1 with the corresponding thiol or NaSR reagent. The isopropa ne thiolate derivative is a dimer in the crystalline form, with four b ridging SPr(i) ligands, and this structure is retained in solution. Re action of 1 with NaSBu(t) afforded the anion [U(cot)(SBu(t))3]- which adopts a three-legged piano-stool configuration.
