Materials Data on LaCeSi2 by Materials Project

CeLaSi2 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. Ce is bonded in a 7-coordinate geometry to seven Si atoms. There are a spread of Ce–Si bond distances ranging from 3.02–3.17 Å. La is bonded in a 7-coordinate geometry to seven Si atoms. There are a spread of La–Si bond distances ranging from 3.04–3.20 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to three equivalent Ce, four equivalent La, and two equivalent Si atoms. Both Si–Si bond lengths are 2.44 Å. In the second Si site, Si is bonded in a 9-coordinate geometry to four equivalent Ce, three equivalent La, and two equivalent Si atoms.
