Materials Data on Mn3Hg by Materials Project

Abstract

Mn3Hg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Mn is bonded to eight equivalent Mn and four equivalent Hg atoms to form distorted MnMn8Hg4 cuboctahedra that share corners with twelve equivalent MnMn8Hg4 cuboctahedra, edges with eight equivalent HgMn12 cuboctahedra, edges with sixteen equivalent MnMn8Hg4 cuboctahedra, faces with four equivalent HgMn12 cuboctahedra, and faces with fourteen equivalent MnMn8Hg4 cuboctahedra. All Mn–Mn bond lengths are 2.84 Å. All Mn–Hg bond lengths are 2.84 Å. Hg is bonded to twelve equivalent Mn atoms to form HgMn12 cuboctahedra that share corners with twelve equivalent HgMn12 cuboctahedra, edges with twenty-four equivalent MnMn8Hg4 cuboctahedra, faces with six equivalent HgMn12 cuboctahedra, and faces with twelve equivalent MnMn8Hg4 cuboctahedra.
