Actinide-Pnictide (An-Pn) Bonds Spanning Non-Metal, Metalloid, and Metal Combinations (An=U, Th; Pn=P, As, Sb, Bi).

ABSTRACT: The synthesis and characterisation is presented of the compounds [An(Tren^DMBS ){Pn(SiMe₃ )₂ }] and [An(Tren^TIPS ){Pn(SiMe₃ )₂ }] [Tren^DMBS =N(CH₂ CH₂ NSiMe₂ Bu^t )₃ , An=U, Pn=P, As, Sb, Bi; An=Th, Pn=P, As; Tren^TIPS =N(CH₂ CH₂ NSiPrⁱ₃ )₃ , An=U, Pn=P, As, Sb; An=Th, Pn=P, As, Sb]. The U-Sb and Th-Sb moieties are unprecedented examples of any kind of An-Sb molecular bond, and the U-Bi bond is the first two-centre-two-electron (2c-2e) one. The Th-Bi combination was too unstable to isolate, underscoring the fragility of these linkages. However, the U-Bi complex is the heaviest 2c-2e pairing of two
