Synthesis and Crystal Structures of the First Antimony(III) Aziridinides

The 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 ava...

Zusammenfassung:The 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.
