Materials Data on LaCuSi by Materials Project
LaCuSi crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. La3+ is bonded to six equivalent Si4- atoms to form a mixture of corner, edge, and face-sharing LaSi6 octahedra. The corner-sharing octahedral tilt angles are 45°. All La–Si bond lengths are 3.20 Å. Cu1+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Cu–Si bond lengths are 2.46 Å. Si4- is bonded in a 9-coordinate geometry to six equivalent La3+ and three equivalent Cu1+ atoms.
