Materials Data on Ce2Si3 by Materials Project
Ce2Si3 crystallizes in the orthorhombic Imm2 space group. The structure is three-dimensional. there are two inequivalent Ce sites. In the first Ce site, Ce is bonded in a 8-coordinate geometry to eight Si atoms. There are a spread of Ce–Si bond distances ranging from 3.02–3.13 Å. In the second Ce site, Ce is bonded in a 10-coordinate geometry to ten Si atoms. There are a spread of Ce–Si bond distances ranging from 3.06–3.19 Å. There are three inequivalent Si sites. In the first Si site, Si is bonded in a 7-coordinate geometry to six Ce and one Si atom. The Si–Si bond length is 2.33 Å. In the second Si site, Si is bonded in a 8-coordinate geometry to six Ce and two equivalent Si atoms. Both Si–Si bond lengths are 2.35 Å. In the third Si site, Si is bonded in a 9-coordinate geometry to six Ce and three Si atoms.
