Materials Data on PrDyC4 by Materials Project

Abstract

DyPrC4 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Dy3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are two shorter (2.54 Å) and eight longer (2.75 Å) Dy–C bond lengths. Pr3+ is bonded in a distorted q4 geometry to ten C+1.50- atoms. There are two shorter (2.54 Å) and eight longer (2.75 Å) Pr–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 four equivalent Dy3+, one Pr3+, and one C+1.50- atom. The C–C bond length is 1.29 Å. In the second C+1.50- site, C+1.50- is bonded in a 6-coordinate geometry to one Dy3+, four equivalent Pr3+, and one C+1.50- atom. The C–C bond length is 1.31 Å.
