The fluxional behaviour of [Ir 4 (CO) 11 ( t ‐BuNC)] ( 1 ) and [Ir 4 (CO) 11 (ArNC)] (Ar = 4‐methoxyphenyl, 4‐tolyl, phenyl, 4‐chlorophenyl, 4‐nitrophenyl; 2 – 5 ) has been investigated by 2D and variable‐temperature 13 C‐NMR. These techniques give new evidence of the processes responsible for CO exchange, namely two successive merry‐go‐rounds causing Cotton ‐like scrambling and a CO rotation about one metal center.
