N2  - Crystallization of 1 : 2 mixtures of the copper(I) halides CuX, X = Cl, Br, I, with triphenylstibine from acetonitrile yields adducts of 1 : 2 CuX/SbPh3 stoichiometry, confirmed by single-crystal X-ray structure determinations. The three complexes are isomorphous, monoclinic, P 21/c, a &#x2248; 24&#183;3, b &#x2248; 14&#183;2, c &#x2248; 20 &#197;, &#946; 110&#176;, Z = 4 dimers; conventional R on F were 0&#183;047, 0&#183;044 and 0&#183;045 for No 11247, 4673 and 10418 independent &#8216;observe&#8217; (I &#62; 3&#963;(I)) reflections respectively. The complexes, also isomorphous with some related species, e.g. 1 : 2 AgBr,I/AsPh3, are dimers: &#91;(Ph3Sb)2Cu(&#181;-X)2Cu(SbPh3)2&#93;. The chloride is also recorded as a chloroform disolvate, isomorphous with its arsine analogue, being monoclinic, C 2/c, a 21&#183;486(9), b 17&#183; 925(9), c 19&#183;972(7) &#197;, &#946; 91&#183;31(3)&#176;, Z = 4 dimers, R 0&#183;057 for No 3756. The far-infrared spectra of &#91;(Ph3Sb)2Cu(&#181;-X)2Cu(SbPh3)2&#93; (X = Br, I) showed no clear v(CuX) bands, in contrast to the situation reported previously for the corresponding Ph3As compounds. A possible v(CuCl) band is observed in the X = Cl complex at 219 cm-1 , but this occurs in a region where there is also significant absorption in the other two compounds. The absence of strong v(CuX) bands in these complexes is consistent with the situation observed previously for the 3 : 1 compounds &#91;(Ph3Sb)3CuX&#93;.
