Materials Data on PrRe2SiC by Materials Project
PrRe2SiC crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Pr is bonded in a 4-coordinate geometry to three equivalent Si and four equivalent C atoms. There are one shorter (3.04 Å) and two longer (3.17 Å) Pr–Si bond lengths. All Pr–C bond lengths are 2.78 Å. Re is bonded in a single-bond geometry to three equivalent Si and one C atom. There are one shorter (2.51 Å) and two longer (2.54 Å) Re–Si bond lengths. The Re–C bond length is 1.97 Å. Si is bonded in a 9-coordinate geometry to three equivalent Pr and six equivalent Re atoms. C is bonded to four equivalent Pr and two equivalent Re atoms to form a mixture of edge and corner-sharing CPr4Re2 octahedra. The corner-sharing octahedral tilt angles are 20°.
