Materials Data on CeNdSi2 by Materials Project
NdCeSi2 crystallizes in the orthorhombic Pmc2_1 space group. The structure is three-dimensional. Nd is bonded in a 7-coordinate geometry to seven Si atoms. There are a spread of Nd–Si bond distances ranging from 3.05–3.23 Å. Ce is bonded in a 7-coordinate geometry to seven Si atoms. There are a spread of Ce–Si bond distances ranging from 3.05–3.22 Å. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to four equivalent Nd, three equivalent Ce, and two equivalent Si atoms. Both Si–Si bond lengths are 2.50 Å. In the second Si site, Si is bonded in a 9-coordinate geometry to three equivalent Nd, four equivalent Ce, and two equivalent Si atoms.
