Title: Materials Data on Ho12(MnC3)5 by Materials Project

Abstract

Ho12(MnC3)5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are three inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded in a rectangular see-saw-like geometry to four C+3.07- atoms. All Ho–C bond lengths are 2.51 Å. In the second Ho3+ site, Ho3+ is bonded to five C+3.07- atoms to form distorted HoC5 square pyramids that share corners with three equivalent HoC5 square pyramids, edges with four equivalent HoC8 hexagonal bipyramids, and an edgeedge with one HoC5 square pyramid. There are a spread of Ho–C bond distances ranging from 2.36–2.54 Å. In the third Ho3+ site, Ho3+ is bonded to eight C+3.07- atoms to form distorted HoC8 hexagonal bipyramids that share corners with four equivalent HoC8 hexagonal bipyramids, edges with two equivalent HoC8 hexagonal bipyramids, and edges with eight equivalent HoC5 square pyramids. There are a spread of Ho–C bond distances ranging from 2.52–2.75 Å. There are two inequivalent Mn2+ sites. In the first Mn2+ site, Mn2+ is bonded in a distorted trigonal non-coplanar geometry to three C+3.07- atoms. There is one shorter (1.79 Å) and two longer (1.90 Å) Mn–C bond length. In the second Mn2+ site, Mn2+ is bonded in a trigonal planarmore » geometry to three equivalent C+3.07- atoms. All Mn–C bond lengths are 1.78 Å. There are four inequivalent C+3.07- sites. In the first C+3.07- site, C+3.07- is bonded in a 4-coordinate geometry to four Ho3+, one Mn2+, and one C+3.07- atom. The C–C bond length is 1.35 Å. In the second C+3.07- site, C+3.07- is bonded to four Ho3+ and two equivalent Mn2+ atoms to form CHo4Mn2 octahedra that share corners with four equivalent CHo4Mn2 octahedra and edges with four equivalent CHo5Mn octahedra. The corner-sharing octahedra tilt angles range from 2–33°. In the third C+3.07- site, C+3.07- is bonded in a 5-coordinate geometry to four Ho3+ and one C+3.07- atom. In the fourth C+3.07- site, C+3.07- is bonded to five Ho3+ and one Mn2+ atom to form a mixture of distorted corner and edge-sharing CHo5Mn octahedra. The corner-sharing octahedra tilt angles range from 9–42°.« less
