Materials Data on Tb2CI by Materials Project
Tb2CI is H-Phase structured and crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Tb is bonded to three equivalent C and three equivalent I atoms to form a mixture of distorted face, edge, and corner-sharing TbC3I3 octahedra. The corner-sharing octahedra tilt angles range from 0–39°. All Tb–C bond lengths are 2.53 Å. All Tb–I bond lengths are 3.27 Å. C is bonded to six equivalent Tb atoms to form edge-sharing CTb6 octahedra. I is bonded in a 6-coordinate geometry to six equivalent Tb atoms.
