Materials Data on CeCoSi2 by Materials Project
CeCoSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce4+ is bonded in a 10-coordinate geometry to ten Si4- atoms. There are a spread of Ce–Si bond distances ranging from 3.07–3.20 Å. Co4+ is bonded in a 5-coordinate geometry to five Si4- atoms. There are a spread of Co–Si bond distances ranging from 2.27–2.35 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a 12-coordinate geometry to four equivalent Ce4+ and four equivalent Co4+ atoms. In the second Si4- site, Si4- is bonded in a 9-coordinate geometry to six equivalent Ce4+, one Co4+, and two equivalent Si4- atoms. Both Si–Si bond lengths are 2.42 Å.
