Sb102− and Sb22− found in [K(18-crown-6)]6[Sb10] [Sb4{Mo(CO)3}2]·2en: two missing family members

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.
