摘要：

The fluxional behaviour of [Ir4(CO)11(t-BuNC)] (1) and [Ir4(CO)11(ArNC)] (Ar = 4-methoxyphenyl, 4-tolyl, phenyl, 4-chlorophenyl, 4-nitrophenyl; 2-5) has been investigated by 2D and variable-temperature C-13-NMR. These techniques give new evidence of the process responsible for CO exchange, namely two successive merry-go-rounds causing Cotton-like scrambling and a CO rotation about one metal center.
