Abstract

Reaction of KMnSb and C₇H₈Mo(CO)₃ produced Sb₁₀²⁻ and Sb₂²⁻ found in [K(18-crown-6)]₆[Sb₁₀][Sb₄{Mo(CO)₃}₂]·2en (1·2en) adding two new family members for antimony polyanions. The unusually short Sb–Sb bond in the Sb₂ subunits of 1 reveals the formation of the second doubly bonded diatomic anion between heavy elements following Bi₂²⁻, and the first example of such doubly bonded anions stabilized by metal carbonyl groups.
