ABSTRACT: The structure of [IrCl₂(C₅₈H₅₁N₃P₄)]Cl·5.5CH₃CN or [IrCl₂(NHCHPh)(((dppm)C(N₂dppm))-κ ³P,C,P)]Cl·5.5CH₃CN [3, dppm = bis-(di-phenyl-phos-phino)methane; systematic name: di-chlorido(1,1,3,3,7,7,9,9-octa-phenyl-4,5-di-aza-1,3λ⁵,7λ⁴,9-tetra-phosphanona-3,5-dien-6-yl-κ² P ¹,P ⁹)-(phenyl-methanimine-κN)iridium(III) chloride aceto-nitrile hemihendeca-solvate], resulting from an oxygen-mediated cleavage of a triazeneyl-idene-phospho-rane ligand producing a diazo-methyl-ene-phospho-rane and a nitrene moiety, which in turn rearrange via a Staudinger reaction and a 1,2-hydride shift to the
