Article abstract of DOI:10.1039/DT9940001685

While the reaction of the monophosphaalkene <(2,4,6-tri-tert-butylphenyl)phosphanediylmethyl>benzene (L2) with copper(I) chloride led to a dimeric complex 22(NCMe)2> 1, use of the diphosphaalkene 1,3-bis<(2,4,6-tri-tert-butylphenyl)phosphanediylmethyl>benzene (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.
