Materials Data on CeRe2SiC by Materials Project

Abstract

CeRe2SiC crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Ce is bonded in a 4-coordinate geometry to three equivalent Si and four equivalent C atoms. There are one shorter (3.07 Å) and two longer (3.14 Å) Ce–Si bond lengths. All Ce–C bond lengths are 2.75 Å. Re is bonded in a single-bond geometry to three equivalent Si and one C atom. There are one shorter (2.50 Å) and two longer (2.52 Å) Re–Si bond lengths. The Re–C bond length is 1.96 Å. Si is bonded in a 9-coordinate geometry to three equivalent Ce and six equivalent Re atoms. C is bonded to four equivalent Ce and two equivalent Re atoms to form a mixture of edge and corner-sharing CCe4Re2 octahedra. The corner-sharing octahedral tilt angles are 21°.
