Materials Data on AlNi3 by Materials Project

Abstract

Ni3Al 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 Al atoms to form NiAl4Ni8 cuboctahedra that share corners with twelve equivalent NiAl4Ni8 cuboctahedra, edges with eight equivalent AlNi12 cuboctahedra, edges with sixteen equivalent NiAl4Ni8 cuboctahedra, faces with four equivalent AlNi12 cuboctahedra, and faces with fourteen equivalent NiAl4Ni8 cuboctahedra. All Ni–Ni bond lengths are 2.52 Å. All Ni–Al bond lengths are 2.52 Å. Al is bonded to twelve equivalent Ni atoms to form AlNi12 cuboctahedra that share corners with twelve equivalent AlNi12 cuboctahedra, edges with twenty-four equivalent NiAl4Ni8 cuboctahedra, faces with six equivalent AlNi12 cuboctahedra, and faces with twelve equivalent NiAl4Ni8 cuboctahedra.
