Azidophosphonamido Rhodium(I) and Iridium(I) Complexes: Synthesis, Properties, and Linkage Isomerism

Chemistry – A European Journal, EarlyView.
A family of azidophosphonamido ligands and their corresponding rhodium(I) and iridium(I) complexes were synthesized. The rich reaction chemistry of these species revealed unusual linkage isomerization processes and bonding motifs. M = Rh, Ir; Mes = 2,4,6‐Me3C6H2. ABSTRACT A series of azidophosphonamido rhodium(I) and iridium(I) complexes ([iPr2P(N3R)NR]
