The crystal structure of HgMo6S8. mercury(II) hexamolybdenum octasulfide. is based on (Mo6S8)S6 cluster units (overline{3} 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. https://chefesquipmenters.shop/product-category/cordial-glasses/
