Materials Data on Ho6Ni20P13 by Materials Project
Abstract
Ho6Ni20P13 crystallizes in the hexagonal P-6 space group. The structure is three-dimensional. there are two inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to six P3- atoms to form distorted HoP6 pentagonal pyramids that share corners with four equivalent HoP6 pentagonal pyramids, corners with twelve NiP4 tetrahedra, edges with two equivalent HoP6 pentagonal pyramids, edges with eight NiP4 tetrahedra, and faces with two equivalent HoP6 pentagonal pyramids. There are a spread of Ho–P bond distances ranging from 2.85–2.91 Å. In the second Ho3+ site, Ho3+ is bonded to six P3- atoms to form distorted HoP6 pentagonal pyramids that share corners with four equivalent HoP6 pentagonal pyramids, corners with twelve NiP4 tetrahedra, edges with two equivalent HoP6 pentagonal pyramids, edges with seven NiP4 tetrahedra, and faces with two equivalent HoP6 pentagonal pyramids. There are a spread of Ho–P bond distances ranging from 2.82–2.90 Å. There are eight inequivalent Ni+1.05+ sites. In the first Ni+1.05+ site, Ni+1.05+ is bonded to four P3- atoms to form NiP4 tetrahedra that share corners with four HoP6 pentagonal pyramids, corners with ten NiP4 tetrahedra, an edgeedge with one HoP6 pentagonal pyramid, and edges with three NiP4 tetrahedra. There are a spread of Ni–Pmore »
