Materials Data on CaGaSi by Materials Project
CaGaSi crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. Ca2+ is bonded to six equivalent Si4- atoms to form a mixture of distorted edge, corner, and face-sharing CaSi6 pentagonal pyramids. All Ca–Si bond lengths are 3.26 Å. Ga2+ is bonded in a trigonal planar geometry to three equivalent Si4- atoms. All Ga–Si bond lengths are 2.39 Å. Si4- is bonded in a 3-coordinate geometry to six equivalent Ca2+ and three equivalent Ga2+ atoms.
