Materials Data on TbCoC by Materials Project

TbCoC crystallizes in the tetragonal P4_2/mmc space group. The structure is three-dimensional. Tb3+ is bonded to four equivalent C4- atoms to form a mixture of distorted corner and edge-sharing TbC4 tetrahedra. All Tb–C bond lengths are 2.52 Å. Co1+ is bonded in a linear geometry to two equivalent C4- atoms. Both Co–C bond lengths are 1.81 Å. C4- is bonded to four equivalent Tb3+ and two equivalent Co1+ atoms to form a mixture of corner and edge-sharing CTb4Co2 octahedra. The corner-sharing octahedra tilt angles range from 0–61°.

Materials Data on TbCoC2 by Materials Project

TbCoC2 crystallizes in the orthorhombic Amm2 space group. The structure is three-dimensional. Tb4+ is bonded in a 8-coordinate geometry to eight equivalent C3- atoms. All Tb–C bond lengths are 2.66 Å. Co2+ is bonded in a 4-coordinate geometry to four equivalent C3- atoms. There is two shorter (1.94 Å) and two longer (1.99 Å) Co–C bond length. C3- is bonded in a 7-coordinate geometry to four equivalent Tb4+, two equivalent Co2+, and one C3- atom. The C–C bond length is 1.38 Å.
