[Cu4(μ-dppm)4(μ4-η<sup>1</sup>,η<sup>2</sup>-C.tbd;Câ )]<sup>2+</sup> has been shown by <sup>31</sup>P and <sup>1</sup>H NMR studies to undergo two fluxional processes in solution, the oscillation of the C.tbd;C<sup>2â </sup> unit inside the copper rectangle and the flipping of the diphosphines, and this has been supported by DFT(B3LYP) calculations.
