Abstract

Tm8Rh5C12 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are four inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded in a 5-coordinate geometry to nine C+3.33- atoms. There are a spread of Tm–C bond distances ranging from 2.37–2.77 Å. In the second Tm3+ site, Tm3+ is bonded in a 1-coordinate geometry to nine C+3.33- atoms. There are a spread of Tm–C bond distances ranging from 2.30–2.91 Å. In the third Tm3+ site, Tm3+ is bonded to six C+3.33- atoms to form TmC6 octahedra that share corners with four CTm5C octahedra and faces with two equivalent TmC6 octahedra. The corner-sharing octahedra tilt angles range from 43–105°. There are a spread of Tm–C bond distances ranging from 2.54–2.62 Å. In the fourth Tm3+ site, Tm3+ is bonded in a 4-coordinate geometry to four C+3.33- atoms. There are two shorter (2.61 Å) and two longer (2.90 Å) Tm–C bond lengths. There are three inequivalent Rh+3.20+ sites. In the first Rh+3.20+ site, Rh+3.20+ is bonded in a linear geometry to two equivalent C+3.33- atoms. Both Rh–C bond lengths are 1.96 Å. In the second Rh+3.20+ site, Rh+3.20+ is bonded in a linear geometry to two C+3.33- atoms.more »« less
