Materials Data on CaZnSi by Materials Project
CaZnSi crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent Si4- atoms to form a mixture of corner, edge, and face-sharing CaSi6 octahedra. The corner-sharing octahedral tilt angles are 45°. All Ca–Si bond lengths are 3.20 Å. Zn2+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Zn–Si bond lengths are 2.45 Å. Si4- is bonded in a 3-coordinate geometry to six equivalent Ca2+ and three equivalent Zn2+ atoms.
