Literature Information
Hong-Zhe Sun, David Balcells, Feliu Maseras, Odile Eisenstein
[Cu4(μ-dppm)4(μ4-η1,η2-CC–)]2+ has been shown by 31P and 1H NMR studies to undergo two fluxional processes in solution, the oscillation of the CC2− unit inside the copper rectangle and the flipping of the diphosphines, and this has been supported by DFT(B3LYP) calculations.
