N2  - The syntheses and room-temperature single-crystal X-ray structure determination of 1 : 3 adducts formed between silver(I) (pseudo-)halides, AgX, and triphenylarsine, AsPh3, are described (X = Cl, Br, I, SCN), &#91;(Ph3As)3AgX&#93;, (1)&#8211;(4). The chloride (1) has been previously described as its acetone hemisolvate; other solvates (1a&#8211;d) (0&#183;75 MeCN, MeOH, 1&#183;5 pyridine, 0&#183;75 2,6-dimethylpyridine) are isomorphous, being triclinic, P-1, a &#x2248; 13&#183;5, b &#x2248; 14&#183;0, c &#x2248; 14&#183;25 &#197;, &#945; &#x2248; 83, &#946; &#x2248; 87, &#947; &#x2248; 76&#176;, V &#x2248; 2600 &#197;3, Z = 2 f.u. The bromide (2), iodide (3) and thiocyanate (4) are isomorphous with &#91;(Ph3P)3AgI&#93;, monoclinic, P21/n, a &#x2248; 19&#183;1, b &#x2248; 14&#183;0, c &#x2248; 17&#183;7 &#197;, &#946; &#x2248; 97&#176;, Z = 4 f.u. In the chlorides, Ag&#8211;Cl are 2&#183;494(5)&#8211;2&#183;525(6) &#197;, with appreciably different Cl&#8211;Ag&#8211;As ranges (99&#183;7(1)&#8211;114&#183;3(1)&#176; in the acetonitrile solvate; 104&#183;8(2)&#8211;110&#183;2(1)&#176; in the 2,6-dimethylpyridine solvate) and more compact As&#8211;Ag&#8211;As distributions (overall range: 109&#183;93(8)&#8211;113&#183;26(3)&#176;). For the bromide and iodide, Ag&#8211;X are 2&#183;627(1) and 2&#183;779(1) &#197; respectively, while for the thiocyanate Ag&#8211;S is 2&#183;550(5) &#197; with Ag&#8211;S&#8211;C 104&#183;2(3)&#176;; the latter complexes also display wide ranges for many of the associated bonding parameters about the silver atom. The far-infrared spectra of &#91;(Ph3As)3AgX&#93; (X = Cl, Br, I) show v(AgX) bands at 217, 145 and 124 cm-1 respectively. The relationship between the v(AgX) wavenumbers and the Ag&#8211;X bond length r (AgX) is found to be the same as that for a range of AgX complexes with phosphine ligands, and is similar to that observed previously for analogous CuX complexes.
