The binuclear complex {Cu(mu-C CPh)(triphos)}(2) [triphos=(PPh2CH2)(3)CMe] has been obtained from a reaction between {Cu(C=CPh)}(n) and triphos. The two copper atoms are bridged unsymmetrically by two C=CPh groups, each attached through one carbon only [Cu-C, 2.016(4) angstrom], the separation between the two coppers being 2.4663(8) angstrom. Only two of the three phosphorus atoms in each ligand are coordinated to copper [Cu-P(1,2) 2.281, 2.273(1) A]. The observed structure may be rationalised using a recent theoretical study [C. Mealli, S.S.M.C. Godinho, M.J. Calhorda, Organometallics 20 (2001) 1734] and differs from that assumed for the rationalisation of its luminescence properties [V. Pawlowski, G. Knor, C. Lennartz, A. Vogler, Eur. J. Inorg. Chem. (2005) 3167]. (c) 2006 Elsevier B.V. All rights reserved.
