F-Element Zintl Chemistry: Actinide-Mediated Dehydrocoupling of H₂Sb^1- Affords the Trithorium and Triuranium Undeca-Antimontriide Zintl Clusters [{An(Tren^TIPS)}₃(μ₃-Sb₁₁)] (An = Th, U; Tren^TIPS = {N(CH₂CH₂NSiⁱPr₃)₃}^3-).

ABSTRACT: Reaction of the cesium antimonide complex [Cs(18C6)₂][SbH₂] (1, 18C6 = 18-crown-6 ether) with the triamidoamine actinide separated ion pairs [An(Tren^TIPS)(L)][BPh₄] (Tren^TIPS = {N(CH₂CH₂NSiⁱPr₃)₃}^3-; An/L = Th/DME (2Th); U/THF (2U)) affords the triactinide undeca-antimontriide Zintl clusters [{An(Tren^TIPS)}₃(μ₃-Sb₁₁)] (An = Th (3Th), U (3U)) by dehydrocoupling. Clusters 3Th and 3U provide two new examples of the Sb₁₁^3- Zintl trianion and are unprecedented examples of molecular Sb₁₁^3- being coordinated to anything since all previous repo
