Materials Data on YHoC4 by Materials Project
HoYC4 crystallizes in the orthorhombic Cmmm space group. The structure is three-dimensional. Ho3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are two shorter (2.45 Å) and eight longer (2.67 Å) Ho–C bond lengths. Y3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are two shorter (2.45 Å) and eight longer (2.67 Å) Y–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 two equivalent Ho3+, three equivalent Y3+, 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 three equivalent Ho3+, two equivalent Y3+, and one C+1.50- atom. The C–C bond length is 1.30 Å.
