Abstract
While the reaction of the monophosphaalkene -tri-tert-butylphenyl)phos phanediylmethyl]-benzene (L2) with copper(I) chloride ed to a dimeric complex [Cu2Cl2L22(NCMe)2] 1, use of the diphosphaalkene 6-tri-tert-bu tylphenyl)phosphanediylmethyl]benzene (L1) gave rise to a tetrameric c omplex [Cu4Cl4L12].3EtOH 2. The crystal structures of the complexes ha ve been determined and indicate that 1 is a centrosymmetric dimer with tetrahedrally co-ordinated copper(I) centres, whereas 2 adopts a 'cub ane-like' structure with pairs of copper atoms bridged by different L1 units.
