Abstract

Ho4C7 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are four inequivalent Ho3+ sites. In the first Ho3+ site, Ho3+ is bonded to six C+1.71- atoms to form distorted HoC6 octahedra that share corners with two equivalent HoC7 octahedra and edges with seven HoC6 octahedra. The corner-sharing octahedra tilt angles range from 2–4°. There are a spread of Ho–C bond distances ranging from 2.49–2.66 Å. In the second Ho3+ site, Ho3+ is bonded in a 8-coordinate geometry to eight C+1.71- atoms. There are a spread of Ho–C bond distances ranging from 2.42–2.66 Å. In the third Ho3+ site, Ho3+ is bonded in a 8-coordinate geometry to nine C+1.71- atoms. There are a spread of Ho–C bond distances ranging from 2.39–2.92 Å. In the fourth Ho3+ site, Ho3+ is bonded to seven C+1.71- atoms to form distorted HoC7 octahedra that share corners with two equivalent HoC6 octahedra, corners with two CHo4C trigonal bipyramids, and edges with five HoC6 octahedra. The corner-sharing octahedra tilt angles range from 2–4°. There are a spread of Ho–C bond distances ranging from 2.44–3.06 Å. There are seven inequivalent C+1.71- sites.
