[Me4N]3[(WOS3)2Ag]·MeCN – An Acetonitrile Solvate with Linear Complex Anions

Abstract

The title compound was prepared by the reaction of [Me4N]2WOS3 with AgCN in MeCN at room temperature and slow crystallisation 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) Å , Z = 8. The crystal structure was determined from single crystal diffractometer data (Mo-Kα radiation) and refined to R = 0.077. The structure is composed of mixed double layers containing the linear trinuclear anion [(WOS3)2Ag]3− and cations separated by a layer formed by cations and solvating acetonitrile molecules.
