%X The syntheses of adducts, &#91;(Ph3Sb)3CuX&#93;, X = Br, I, NO3, obtained by crystallization of 1 : 3 CuX/SbPh3 mixtures from appropriate solvents are described, together with their room-temperature single-crystal X-ray structure determinations. The bromide, obtained as a chloroform monosolvate from that solvent, is triclinic, P-1, a 13&#183;861(4), b 14&#183;306(4), c 14&#183;347(4) &#197;, &#945; 84&#183;40(2), &#946; 86&#183;93(2), &#947; 75&#183;56(2)&#176;, Z = 2 f.u., conventional R on F being 0&#183;053 for No = 4136 independent &#8216;observed&#8217; (I &#62; 3&#963;(I)) reflections; this solvate is isomorphous with its previously recorded chloride counterpart. The iodide is triclinic, P-1, a 14&#183;55(1), b 14&#183;385(2), c 23&#183;626(6) &#197;, &#945; 91&#183;78(1),  &#946; 90&#183;77(4), &#947; 92&#183;54(5)&#176;; Z= 4, R 0&#183;050 for No 6917, and isomorphous with its phosphorus counterpart. The nitrate, although a methanol sesquisolvate, is also isomorphous with the chloride and bromide, a 13&#183;369(9), b 14&#183;398(3), c 14&#183; 504(12) &#197;, &#945; 82&#183;29(5), &#946; 84&#183;39(6), &#947; 75&#183;11(4)&#176;, R 0&#183;052 for No 5672. Cu-X are (2&#183;235(5) (Cl)), 2&#183;366(3) (Br), 2&#183; 556(2) ( 2 ) (I), 1&#183;98(1) &#197; (ONO2), appreciably shorter than in their previously recorded EPh3, E = P, As counterparts. The far-infrared spectra of &#91;(Ph3Sb)3CuX&#93; showed no clear v(CuX) bands, in contrast to the situation reported previously for the corresponding Ph3P and Ph3As compounds. It is likely that v(CuCl) is masked by a strong band at 270 cm-1 due to the Ph3Sb ligand. However, the region below 250 cm-1 in which the v(CuX) bands are expected for the X = Br, I complexes contains no strong ligand bands. Possible reasons for the absence of v(CuX) bands in these complexes are considered.
