Materials Data on TaNi3 by Materials Project
Ni3Ta is beta Cu3Ti structured and crystallizes in the orthorhombic Pmmn space group. The structure is three-dimensional. Ta is bonded to twelve Ni atoms to form TaNi12 cuboctahedra that share corners with two equivalent TaNi12 cuboctahedra, corners with sixteen NiTa4Ni8 cuboctahedra, edges with six equivalent TaNi12 cuboctahedra, edges with twelve equivalent NiTa4Ni8 cuboctahedra, faces with six equivalent TaNi12 cuboctahedra, and faces with fourteen NiTa4Ni8 cuboctahedra. There are a spread of Ta–Ni bond distances ranging from 2.56–2.64 Å. There are two inequivalent Ni sites. In the first Ni site, Ni is bonded to four equivalent Ta and eight equivalent Ni atoms to form distorted NiTa4Ni8 cuboctahedra that share corners with eight equivalent TaNi12 cuboctahedra, corners with ten NiTa4Ni8 cuboctahedra, edges with eighteen NiTa4Ni8 cuboctahedra, faces with six equivalent TaNi12 cuboctahedra, and faces with fourteen NiTa4Ni8 cuboctahedra. There are a spread of Ni–Ni bond distances ranging from 2.52–2.69 Å. In the second Ni site, Ni is bonded to four equivalent Ta and eight Ni atoms to form distorted NiTa4Ni8 cuboctahedra that share corners with four equivalent TaNi12 cuboctahedra, corners with fourteen NiTa4Ni8 cuboctahedra, edges with six equivalent TaNi12 cuboctahedra, edges with twelve NiTa4Ni8 cuboctahedra, faces with four equivalent TaNi12 cuboctahedra, and faces with sixteen NiTa4Ni8 cuboctahedra. There are a spread of Ni–Ni bond distances ranging from 2.55–2.57 Å.
