Materials Data on TbDyC4 by Materials Project
DyTbC4 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Dy3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are a spread of Dy–C bond distances ranging from 2.46–2.69 Å. Tb3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are two shorter (2.47 Å) and eight longer (2.69 Å) Tb–C bond lengths. There are two inequivalent C+1.50- sites. In the first C+1.50- site, C+1.50- is bonded in a 6-coordinate geometry to three equivalent Dy3+, two equivalent Tb3+, and one C+1.50- atom. The C–C bond length is 1.30 Å. In the second C+1.50- site, C+1.50- is bonded in a 6-coordinate geometry to two equivalent Dy3+, three equivalent Tb3+, and one C+1.50- atom.
