Reactions of a Zn(i) complex with group 14 azides – formation of zinc azide and zinc hexazene complexes

Abstract

Two zinc hexazene complexes L₂Zn₂(μ-1,6-R₂-N₆) (L = HC[C(Me)N(2,4,6-Me₃C₆H₂)]₂; R = Ph (3), Dipp = 2,6-i-Pr₂C₆H₃ (4)), were synthesized by reaction of the Zn(I) complex L₂Zn₂ (1) with phenyl azide and 2,6-diisopropylphenyl azide, respectively. 3 represents the second structurally characterized transition metal hexazene complex. In contrast, reactions of 1 with Me₃MN₃ (M = Si, Sn) yielded the azido complex [LZn(μ-N₃)]₂ (2) and Me₃M-MMe₃.
