Na_2.54Cs_1.14Mo₉S₁₁, a quaternary reduced molybdenum sulfide containing Mo₉ clusters

D. Salloum, P. Gougeon and M. Potel

Abstract: Sodium caesium nonamolybdenum undecasulfide, Na_2.54Cs_1.14Mo₉S₁₁, is isostructural with Ag_1.91Cs_1.16Mo₉S₁₁. Its crystal structure consists of Mo₉S₁₁S₆ cluster units with crystallographic (C_3h) symmetry and interconnected through interunit Mo-S bonds. The Mo-S framework delimits channels in which the Cs⁺ cations are disordered. The Na⁺ cations are located on the mirror planes around the threefold axis between two consecutive Mo₉S₁₁S₆ units.
