Abstract

Er12(ReC3)5 crystallizes in the hexagonal P-62m space group. The structure is three-dimensional. there are three inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to five C+3.47- atoms to form distorted ErC5 square pyramids that share corners with three equivalent ErC5 square pyramids, edges with four equivalent ErC8 hexagonal bipyramids, and an edgeedge with one ErC5 square pyramid. There are a spread of Er–C bond distances ranging from 2.31–2.54 Å. In the second Er3+ site, Er3+ is bonded to eight C+3.47- atoms to form distorted ErC8 hexagonal bipyramids that share corners with four equivalent ErC8 hexagonal bipyramids, edges with two equivalent ErC8 hexagonal bipyramids, and edges with eight equivalent ErC5 square pyramids. There are a spread of Er–C bond distances ranging from 2.54–2.78 Å. In the third Er3+ site, Er3+ is bonded in a rectangular see-saw-like geometry to four C+3.47- atoms. There are two shorter (2.49 Å) and two longer (2.52 Å) Er–C bond lengths. There are two inequivalent Re+3.20+ sites. In the first Re+3.20+ site, Re+3.20+ is bonded in a distorted T-shaped geometry to three C+3.47- atoms. There are one shorter (1.94 Å) and two longer (2.06 Å) Re–C bond lengths.
