Materials Data on CeSi2Pt by Materials Project
CePtSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce3+ is bonded in a 10-coordinate geometry to ten Si4- atoms. There are a spread of Ce–Si bond distances ranging from 3.14–3.25 Å. Pt5+ is bonded in a 5-coordinate geometry to five Si4- atoms. There are a spread of Pt–Si bond distances ranging from 2.41–2.44 Å. There are two inequivalent Si4- sites. In the first Si4- site, Si4- is bonded in a distorted single-bond geometry to six equivalent Ce3+, one Pt5+, and two equivalent Si4- atoms. Both Si–Si bond lengths are 2.41 Å. In the second Si4- site, Si4- is bonded in a 4-coordinate geometry to four equivalent Ce3+ and four equivalent Pt5+ atoms.
