Materials Data on CeSi2Ag by Materials Project
Abstract
CeAgSi2 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 10-coordinate geometry to four equivalent Ag and ten Si atoms. There are two shorter (3.44 Å) and two longer (3.48 Å) Ce–Ag bond lengths. There are a spread of Ce–Si bond distances ranging from 3.07–3.20 Å. Ag is bonded to four equivalent Ce, four equivalent Ag, and four equivalent Si atoms to form a mixture of distorted corner and face-sharing AgCe4Si4Ag4 cuboctahedra. All Ag–Ag bond lengths are 2.97 Å. There are two shorter (2.59 Å) and two longer (2.64 Å) Ag–Si bond lengths. There are two inequivalent Si sites. In the first Si site, Si is bonded in a 9-coordinate geometry to six equivalent Ce and three Si atoms. There are one shorter (2.32 Å) and two longer (2.38 Å) Si–Si bond lengths. In the second Si site, Si is bonded in a 9-coordinate geometry to four equivalent Ce, four equivalent Ag, and one Si atom.
