Materials Data on LuCuSi by Materials Project
LuCuSi crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Lu3+ is bonded to six equivalent Si4- atoms to form a mixture of corner, edge, and face-sharing LuSi6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Lu–Si bond lengths are 2.98 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Cu–Si bond lengths are 2.37 Å. Si4- is bonded in a 9-coordinate geometry to six equivalent Lu3+ and three equivalent Cu1+ atoms.
