N2  - Syntheses and room-temperature single-crystal X-ray structural characterization of binuclear 1 : 2 adducts formed between silver(I) halides, AgX (X = Cl, Br, I), and triphenylstibine, SbPh3, are described. The three complexes are isomorphous, being triclinic, P-1, a &#x2248; 18&#183;5, b &#x2248; 14&#183;6, c &#x2248; 14&#183;5 &#197;, &#945; &#x2248; 62&#183;5, &#946; &#x2248; 74, &#947; &#x2248; 77&#176;, Z = 2 centrosymmetric dimers. Conventional R on F were 0&#183;043, 0&#183;038 and 0&#183;046 for 4984, 8479 and 4166 independent, &#8216;observed&#8217; (I &#62; 3&#963;(I)) reflections respectively. In &#91;(Ph3b)2Ag(&#181;-X)2Ag(SbPh3)2&#93;, Ag&#8211;Sb range between 2&#183;702(1) and 2&#183;744(2) &#197;, lengthening slightly from chloride to iodide; Ag&#8211;X are 2&#183;567(5)&#8211;2&#183;628(4) (Cl), 2&#183;684(1)&#8211;2&#183;737(1) (Br) and 2&#183;826(3)&#8211;2&#183;869(3) &#197; (I). The far-infrared spectra of &#91;(Ph3Sb)2Ag(&#181;-X)2Ag(SbPh3)2&#93; show v(AgX) bands at 178, 158 (X = Cl), 121 (X = Br) and 110 cm-1 (X = I). The splittings and band widths reflect a decrease in the degree of distortion of the Ag(&#181;-X)2Ag units from a symmetrically bridged structure from X = Cl to I.
