Materials Data on EuC10 by Materials Project

EuC10 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Eu2+ is bonded in a 6-coordinate geometry to twenty-two C+0.20- atoms. There are a spread of Eu–C bond distances ranging from 2.98–3.29 Å. There are three inequivalent C+0.20- sites. In the first C+0.20- site, C+0.20- is bonded in a 3-coordinate geometry to three equivalent Eu2+ and three C+0.20- atoms. All C–C bond lengths are 1.45 Å. In the second C+0.20- site, C+0.20- is bonded in a 3-coordinate geometry to two equivalent Eu2+ and three C+0.20- atoms. There is one shorter (1.43 Å) and two longer (1.45 Å) C–C bond length. In the third C+0.20- site, C+0.20- is bonded in a distorted trigonal planar geometry to two equivalent Eu2+ and three C+0.20- atoms.

Materials Data on EuC10 by Materials Project

EuC10 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Eu2+ is bonded to eight C+0.20- atoms to form distorted face-sharing EuC8 hexagonal bipyramids. There are four shorter (2.58 Å) and four longer (2.73 Å) Eu–C bond lengths. There are three inequivalent C+0.20- sites. In the first C+0.20- site, C+0.20- is bonded in a 4-coordinate geometry to one Eu2+ and three C+0.20- atoms. There are a spread of C–C bond distances ranging from 1.39–1.45 Å. In the second C+0.20- site, C+0.20- is bonded in a trigonal planar geometry to three C+0.20- atoms. Both C–C bond lengths are 1.48 Å. In the third C+0.20- site, C+0.20- is bonded in a 4-coordinate geometry to two equivalent Eu2+ and two equivalent C+0.20- atoms.
