Cs2Mo15S19: a novel ternary reduced molybdenum sulfide containing Mo6 and Mo9 clusters
Abstract:The crystal structure of dicaesium pentadecamolybdenum nonadecasulfide, Cs2Mo15S19, consists of a mixture of Mo6S8S6 and Mo9S11S6 cluster units in a 1:1 ratio. Both units are interconnected via inter-unit Mo—S bonds. The Cs+ cations occupy large voids between the different cluster units. The Cs and two inner S atoms lie on sites with 3 symmetry (Wyckoff site 12c) and the Mo and S atoms of the median plane of the Mo9S11S6 cluster unit on sites with 2 symmetry (Wyckoff site 18e).
