Materials Data on Ni3Hg by Materials Project

Abstract

Ni3Hg is Uranium Silicide structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Ni is bonded to eight equivalent Ni and four equivalent Hg atoms to form NiNi8Hg4 cuboctahedra that share corners with twelve equivalent NiNi8Hg4 cuboctahedra, edges with eight equivalent HgNi12 cuboctahedra, edges with sixteen equivalent NiNi8Hg4 cuboctahedra, faces with four equivalent HgNi12 cuboctahedra, and faces with fourteen equivalent NiNi8Hg4 cuboctahedra. All Ni–Ni bond lengths are 2.65 Å. All Ni–Hg bond lengths are 2.65 Å. Hg is bonded to twelve equivalent Ni atoms to form HgNi12 cuboctahedra that share corners with twelve equivalent HgNi12 cuboctahedra, edges with twenty-four equivalent NiNi8Hg4 cuboctahedra, faces with six equivalent HgNi12 cuboctahedra, and faces with twelve equivalent NiNi8Hg4 cuboctahedra.
