While the reaction of the monophosphaalkene benzene (L2) with copper(I) chloride led to a dimeric complex 22(NCMe)2> 1, use of the diphosphaalkene 1,3-bisbenzene (L1) gave rise to a tetrameric complex 12>*3EtOH 2.The crystal structures of the complexes have been determined and indicate that 1 is a centrosymmetric dimer with tetrahedrally co-ordinated copper(I) centres, whereas 2 adopts a 'cubane-like' structure with pairs of copper atoms bridged by different L1 units.
