Materials Data on SrC10 by Materials Project
SrC10 crystallizes in the cubic Im-3 space group. The structure is three-dimensional. Sr2+ is bonded in a 6-coordinate geometry to twenty-two C+0.20- atoms. There are a spread of Sr–C bond distances ranging from 3.03–3.31 Å. There are three inequivalent C+0.20- sites. In the first C+0.20- site, C+0.20- is bonded in a distorted trigonal planar geometry to two equivalent Sr2+ and three C+0.20- atoms. There is one shorter (1.44 Å) and two longer (1.45 Å) C–C bond length. In the second C+0.20- site, C+0.20- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and three C+0.20- atoms. The C–C bond length is 1.43 Å. In the third C+0.20- site, C+0.20- is bonded in a 3-coordinate geometry to three equivalent Sr2+ and three C+0.20- atoms. The C–C bond length is 1.45 Å.
