Materials Data on ErCuSi by Materials Project

ErCuSi crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Er3+ is bonded to six equivalent Si4- atoms to form a mixture of face, edge, and corner-sharing ErSi6 octahedra. The corner-sharing octahedral tilt angles are 47°. All Er–Si bond lengths are 3.01 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 Er3+ and three equivalent Cu1+ atoms.

Materials Data on ErCuSi by Materials Project

ErCuSi crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Er3+ is bonded to six equivalent Si4- atoms to form a mixture of distorted edge, face, and corner-sharing ErSi6 pentagonal pyramids. All Er–Si bond lengths are 3.01 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 Er3+ and three equivalent Cu1+ atoms.
