Materials Data on TmCoC by Materials Project
TmCoC crystallizes in the tetragonal P4_2/mmc space group. The structure is three-dimensional. Tm3+ is bonded to four equivalent C4- atoms to form a mixture of distorted edge and corner-sharing TmC4 tetrahedra. All Tm–C bond lengths are 2.46 Å. Co1+ is bonded in a linear geometry to two equivalent C4- atoms. Both Co–C bond lengths are 1.80 Å. C4- is bonded to four equivalent Tm3+ and two equivalent Co1+ atoms to form a mixture of edge and corner-sharing CTm4Co2 octahedra. The corner-sharing octahedra tilt angles range from 0–62°.
