title: Cs2Mo15S19: a novel ternary reduced molybdenum sulfide containing Mo6 and Mo9 clusters.
abstract: The crystal structure of dicaesium pentadecamolybdenum nonadecasulfide, Cs(2)Mo(15)S(19), consists of a mixture of Mo(6)S(8)S(6) and Mo(9)S(11)S(6) 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 Mo(9)S(11)S(6) cluster unit on sites with 2 symmetry (Wyckoff site 18e).
