Materials Data on CoHg3 by Materials Project

Abstract

CoHg3 is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Co is bonded to twelve equivalent Hg atoms to form CoHg12 cuboctahedra that share corners with twelve equivalent CoHg12 cuboctahedra, edges with twenty-four equivalent HgCo4Hg8 cuboctahedra, faces with six equivalent CoHg12 cuboctahedra, and faces with twelve equivalent HgCo4Hg8 cuboctahedra. All Co–Hg bond lengths are 3.03 Å. Hg is bonded to four equivalent Co and eight equivalent Hg atoms to form HgCo4Hg8 cuboctahedra that share corners with twelve equivalent HgCo4Hg8 cuboctahedra, edges with eight equivalent CoHg12 cuboctahedra, edges with sixteen equivalent HgCo4Hg8 cuboctahedra, faces with four equivalent CoHg12 cuboctahedra, and faces with fourteen equivalent HgCo4Hg8 cuboctahedra. All Hg–Hg bond lengths are 3.03 Å.
