The Materials Project

Tm2Cr2C3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Tm3+ is bonded in a 5-coordinate geometry to five C4- atoms. There are a spread of Tm–C bond distances ranging from 2.41–2.58 Å. Cr3+ is bonded to four C4- atoms to form a mixture of corner and edge-sharing CrC4 trigonal pyramids. There are a spread of Cr–C bond distances ranging from 1.89–2.00 Å. There are two inequivalent C4- sites. In the first C4- site, C4- is bonded in a 6-coordinate geometry to three equivalent Tm3+ and three equivalent Cr3+ atoms. In the second C4- site, C4- is bonded to four equivalent Tm3+ and two equivalent Cr3+ atoms to form edge-sharing CTm4Cr2 octahedra.
