Materials Data on TmRe2SiC by Materials Project

Abstract

TmRe2SiC crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Tm is bonded in a 4-coordinate geometry to three equivalent Si and four equivalent C atoms. There are one shorter (3.03 Å) and two longer (3.11 Å) Tm–Si bond lengths. All Tm–C bond lengths are 2.71 Å. Re is bonded in a single-bond geometry to three equivalent Si and one C atom. There are one shorter (2.47 Å) and two longer (2.49 Å) Re–Si bond lengths. The Re–C bond length is 1.94 Å. Si is bonded in a 9-coordinate geometry to three equivalent Tm and six equivalent Re atoms. C is bonded to four equivalent Tm and two equivalent Re atoms to form a mixture of edge and corner-sharing CTm4Re2 octahedra. The corner-sharing octahedral tilt angles are 20°.
