%X The 1 : 1 adducts between the copper(I) halides, CuX , X = Cl , Br, I, and the title ligand, 'triphos', Ph2P(CH2)2P(Ph)(CH2)2PPh2, have been synthesized and characterized by single-crystal X-ray structure determination. The three complexes are isomorphous : monoclinic P21/c, a &#8776; 14.5, b &#8776; 20.5, c &#8776; 24.5 &#506;, &#946; &#8776; 118.5&#176;; the asymmetric unit of each structure is the binuclear [Cu2X2( triphos )2] unit (with one acetonitrile solvate). Residuals were 0.047, 0.049 and 0.065 for 6006, 4832 and 5108 'observed', independent reflections respectively. About each copper atom, the four-coordinate environment comprises a terminal halogen [Cu- Cl,Br,I , 2.305(3), 2.311(2); 2.441(2), 2.443(2); 2.614(2), 2.614(2)&#506;], two phosphorus atoms (central and distal) from the same ligand , and one distal phosphorus atom from the other ligand.
