Abstract
[Cu4(μ-dppm)4(μ4-η1,η2-C≡C–)]2+ has been shown by 31P and 1H NMR studies to undergo two fluxional processes in solution, the oscillation of the C≡C2- unit inside the copper rectangle and the flipping of the diphosphines, and this has been supported by DFT(B3LYP) calculations. © 2003 The Royal Society of Chemistry.
