M⋯HNR interactions in imino-bound diaryltriazene complexes: structure and fluxionality

Abstract

The nominally square-planar coordination of the d⁸ complexes [MClL¹L²(p-XC₆H₄NNNHC₆H₄X-p)] (M = Rh, L¹ = L² = CO, X = H, Me, Et or F; M = Ir, L¹ = L² = CO, X = Me; M = Pd or Pt, L¹ = Cl, L² = PPh₃, X = Me; M = Pd, L¹L² = η³-C₃H₅, X = Me), with the triazene N-bonded via the imine group, is supplemented by an axial M⋯H–N interaction involving the terminal amino group.
