Materials Data on CaSi2 by Materials Project
Abstract
CaSi2 is alpha boron-derived structured and crystallizes in the trigonal R-3m space group. The structure is three-dimensional. Ca is bonded in a 7-coordinate geometry to seven Si atoms. There are a spread of Ca–Si bond distances ranging from 3.01–3.12 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded to three equivalent Ca and three equivalent Si atoms to form distorted edge-sharing SiCa3Si3 octahedra. All Si–Si bond lengths are 2.39 Å. In the second Si site, Si is bonded in a 7-coordinate geometry to four equivalent Ca and three equivalent Si atoms. All Si–Si bond lengths are 2.44 Å.
