Materials Data on Th2Ru6C5 by Materials Project
Th2Ru6C5 crystallizes in the tetragonal P4/mbm space group. The structure is three-dimensional. Th4+ is bonded in a 6-coordinate geometry to six equivalent C4- atoms. There are two shorter (2.69 Å) and four longer (2.87 Å) Th–C bond lengths. There are three inequivalent Ru2+ sites. In the first Ru2+ site, Ru2+ is bonded in a distorted T-shaped geometry to three C4- atoms. There are one shorter (2.04 Å) and two longer (2.09 Å) Ru–C bond lengths. In the second Ru2+ site, Ru2+ is bonded in a square co-planar geometry to four equivalent C4- atoms. All Ru–C bond lengths are 2.14 Å. In the third Ru2+ site, Ru2+ is bonded in a linear geometry to two equivalent C4- atoms. Both Ru–C bond lengths are 2.10 Å. There are two inequivalent C4- sites. In the first C4- site, C4- is bonded to six Ru2+ atoms to form corner-sharing CRu6 octahedra. The corner-sharing octahedral tilt angles are 0°. In the second C4- site, C4- is bonded in a 7-coordinate geometry to three equivalent Th4+, three Ru2+, and one C4- atom. The C–C bond length is 1.43 Å.
