Ag_1.91Cs_1.16Mo₉S₁₁: a novel quaternary reduced molybdenum sulfide containing Mo₉ clusters

D. Salloum, P. Gougeon and M. Potel

Abstract: Ag_1.911 (6)Cs_1.16 (3)Mo₉S₁₁, silver caesium nonamolybdenum undecasulfide, is isostructural with the archetype h-Mo₉Se₁₁. Its crystal structure consists of Mo₉S₁₁S₆ cluster units centered on the Wyckhoff site 2d and interconnected through inter-unit Mo-S bonds. The Mo-S framework delimits channels in which the Cs⁺ cations are disordered. The Ag atoms are located on mirror planes around the threefold axes between two consecutive Mo₉S₁₁S₆ units.
