[Me ₄N] ₃[(WOS ₃) ₂Ag]·MeCN - An acetonitrile solvate with linear complex anions

The trinuclear complex [Me4N]3[(WOS3)2Ag].MeCN was prepd. by the reaction of [Me4N]2WOS3 with AgCN in MeCN at room temp. followed by slow crystn. in the refrigerator. It was characterized by IR and mass spectroscopy. It crystallizes in the orthorhombic space group Pnma (No. 62) with unit cell dimensions a = 19.648(7), b = 27.878(12), c = 11.494(3) .ANG., Z = 8. The crystal structure was detd. from single crystal diffractometer data (Mo-K radiation) and refined to R = 0.077. The structure is composed of mixed double layers contg. the linear trinuclear anion [(WOS3)2Ag]3- and cations sepd. by a layer formed by cations and solvating acetonitrile mols.
