Materials Data on HoCuSi by Materials Project

HoCuSi crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ho3+ is bonded to six equivalent Si4- atoms to form a mixture of face, edge, and corner-sharing HoSi6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Ho–Si bond lengths are 3.02 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Cu–Si bond lengths are 2.39 Å. Si4- is bonded in a 9-coordinate geometry to six equivalent Ho3+ and three equivalent Cu1+ atoms.

Materials Data on HoCuSi by Materials Project

HoCuSi crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ho3+ is bonded to six equivalent Si4- atoms to form a mixture of distorted face, edge, and corner-sharing HoSi6 pentagonal pyramids. All Ho–Si bond lengths are 3.07 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Cu–Si bond lengths are 2.34 Å. Si4- is bonded in a 9-coordinate geometry to six equivalent Ho3+ and three equivalent Cu1+ atoms.
