Materials Data on Al(Ni4Pt)3 by Materials Project
Abstract
Al(PtNi4)3 is Uranium Silicide-derived structured and crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. there are two inequivalent Pt sites. In the first Pt site, Pt is bonded to twelve Ni atoms to form PtNi12 cuboctahedra that share corners with four equivalent AlNi12 cuboctahedra, corners with eight PtNi12 cuboctahedra, edges with twenty-four NiAl4Ni8 cuboctahedra, a faceface with one AlNi12 cuboctahedra, faces with five PtNi12 cuboctahedra, and faces with twelve NiNi8Pt4 cuboctahedra. There are a spread of Pt–Ni bond distances ranging from 2.56–2.59 Å. In the second Pt site, Pt is bonded to twelve Ni atoms to form PtNi12 cuboctahedra that share corners with twelve PtNi12 cuboctahedra, edges with twenty-four NiNi8Pt4 cuboctahedra, faces with six PtNi12 cuboctahedra, and faces with twelve NiNi8Pt4 cuboctahedra. All Pt–Ni bond lengths are 2.56 Å. There are five inequivalent Ni sites. In the first Ni site, Ni is bonded to eight equivalent Ni and four equivalent Al atoms to form NiAl4Ni8 cuboctahedra that share corners with twelve NiAl4Ni8 cuboctahedra, edges with eight equivalent PtNi12 cuboctahedra, edges with sixteen equivalent NiAl2Ni8Pt2 cuboctahedra, faces with four equivalent AlNi12 cuboctahedra, and faces with fourteen NiAl4Ni8 cuboctahedra. All Ni–Ni bond lengths are 2.53 Å. All Ni–Al bondmore »
