The Chevrel phase HgMo6S8

摘要

The crystal structure of HgMo6S8, mercury(II) hexa­molybdenum octa­sulfide, is based on (Mo6S8)S6 cluster units ( symmetry) inter­connected through inter­unit Mo—S bonds. The Hg²⁺ cations occupy large voids between the different cluster units and are covalently bonded to two S atoms. The Hg atoms and one S atom lie on sites with crystallographic and 3 symmetry, respectively. Refinement of the occupancy factor of the Hg atom led to the composition Hg0.973 (3)Mo6S8.
