Materials Data on Dy12(OsC3)5 by Materials Project
Dy12(OsC3)5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are three inequivalent Dy3+ sites. In the first Dy3+ site, Dy3+ is bonded in a rectangular see-saw-like geometry to four C+1.87- atoms. There are two shorter (2.49 Å) and two longer (2.54 Å) Dy–C bond lengths. In the second Dy3+ site, Dy3+ is bonded to five C+1.87- atoms to form distorted DyC5 square pyramids that share a cornercorner with one CDy4OsC octahedra, corners with three equivalent DyC5 square pyramids, and an edgeedge with one DyC5 square pyramid. The corner-sharing octahedral tilt angles are 42°. There are a spread of Dy–C bond distances ranging from 2.38–2.54 Å. In the third Dy3+ site, Dy3+ is bonded in a 8-coordinate geometry to eight C+1.87- atoms. There are a spread of Dy–C bond distances ranging from 2.56–2.87 Å. There are two inequivalent Os+1.60- sites. In the first Os+1.60- site, Os+1.60- is bonded in a 3-coordinate geometry to three C+1.87- atoms. There is one shorter (1.88 Å) and two longer (2.03 Å) Os–C bond length. In the second Os+1.60- site, Os+1.60- is bonded in a trigonal planar geometry to three equivalent C+1.87- atoms. All Os–C bond lengths are 1.92 Å. There are four inequivalent C+1.87- sites. In the first C+1.87- site, C+1.87- is bonded to four Dy3+, one Os+1.60-, and one C+1.87- atom to form distorted CDy4OsC octahedra that share corners with six CDy4OsC octahedra, corners with two equivalent DyC5 square pyramids, and edges with six CDy5Os octahedra. The corner-sharing octahedra tilt angles range from 44–73°. The C–C bond length is 1.34 Å. In the second C+1.87- site, C+1.87- is bonded to four Dy3+ and two equivalent Os+1.60- atoms to form CDy4Os2 octahedra that share corners with four equivalent CDy4Os2 octahedra and edges with six CDy4OsC octahedra. The corner-sharing octahedra tilt angles range from 1–35°. In the third C+1.87- site, C+1.87- is bonded in a 5-coordinate geometry to four Dy3+ and one C+1.87- atom. In the fourth C+1.87- site, C+1.87- is bonded to five Dy3+ and one Os+1.60- atom to form a mixture of edge and corner-sharing CDy5Os octahedra. The corner-sharing octahedra tilt angles range from 5–73°.
