Materials Data on Tb2B4C by Materials Project
Tb2B4C crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. Tb4+ is bonded in a 2-coordinate geometry to six equivalent B+1.50- and two equivalent C2- atoms. There are four shorter (2.75 Å) and two longer (2.99 Å) Tb–B bond lengths. Both Tb–C bond lengths are 2.43 Å. There are two inequivalent B+1.50- sites. In the first B+1.50- site, B+1.50- is bonded in a 3-coordinate geometry to six equivalent Tb4+ and three B+1.50- atoms. There is one shorter (1.78 Å) and two longer (1.88 Å) B–B bond length. In the second B+1.50- site, B+1.50- is bonded in a single-bond geometry to two equivalent B+1.50- and one C2- atom. The B–C bond length is 1.49 Å. C2- is bonded to four equivalent Tb4+ and two equivalent B+1.50- atoms to form distorted edge-sharing CTb4B2 octahedra.
