Materials Data on ThSiRu2C by Materials Project

ThRu2SiC crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. Th4+ is bonded in a 4-coordinate geometry to three equivalent Si4- and four equivalent C4- atoms. All Th–Si bond lengths are 3.16 Å. All Th–C bond lengths are 2.74 Å. Ru2+ is bonded to three equivalent Si4- and one C4- atom to form a mixture of distorted edge and corner-sharing RuSi3C tetrahedra. All Ru–Si bond lengths are 2.52 Å. The Ru–C bond length is 1.90 Å. Si4- is bonded in a 9-coordinate geometry to three equivalent Th4+ and six equivalent Ru2+ atoms. C4- is bonded to four equivalent Th4+ and two equivalent Ru2+ atoms to form a mixture of edge and corner-sharing CTh4Ru2 octahedra. The corner-sharing octahedral tilt angles are 25°.
