Title: Materials Data on CeSiRh2 by Materials Project

Abstract

CeRh2Si crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 4-coordinate geometry to ten Rh and four equivalent Si atoms. There are a spread of Ce–Rh bond distances ranging from 2.98–3.42 Å. All Ce–Si bond lengths are 3.19 Å. There are two inequivalent Rh sites. In the first Rh site, Rh is bonded in a 5-coordinate geometry to six equivalent Ce, two equivalent Rh, and one Si atom. Both Rh–Rh bond lengths are 2.72 Å. The Rh–Si bond length is 2.37 Å. In the second Rh site, Rh is bonded to four equivalent Ce and four equivalent Si atoms to form a mixture of distorted edge and face-sharing RhCe4Si4 tetrahedra. There are two shorter (2.38 Å) and two longer (2.40 Å) Rh–Si bond lengths. Si is bonded in a 9-coordinate geometry to four equivalent Ce and five Rh atoms.
