Materials Data on LuCoC by Materials Project
LuCoC crystallizes in the tetragonal P4_2/mmc space group. The structure is three-dimensional. Lu3+ is bonded to four equivalent C4- atoms to form a mixture of distorted corner and edge-sharing LuC4 tetrahedra. All Lu–C bond lengths are 2.44 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 Lu3+ and two equivalent Co1+ atoms to form a mixture of corner and edge-sharing CLu4Co2 octahedra. The corner-sharing octahedra tilt angles range from 0–63°.
