first antimony(III) aziridinyl derivatives are reported. Treatment
of anhydrous SbCl3 with N-lithioaziridine Li(Azn) (Azn
= NC2H4) afforded the structurally unique heterobimetallic
lithium/antimony(III) amide complex [Li3Sb(μ3-Cl)2(μ-Azn)4(THF)2]∞ (1). Homoleptic Sb2(Azn)6 (2) has become available for the first time
through an amide group exchange reaction between Sb(NMe2)3 and 3 equiv of aziridine. The low-melting Sb2(Azn)6 exhibits a “weak dimer” structure
in the crystal.
