Materials Data on RbC8 by Materials Project

RbC8 crystallizes in the orthorhombic Fddd space group. The structure is three-dimensional. Rb1+ is bonded to twelve C+0.12- atoms to form edge-sharing RbC12 cuboctahedra. There are eight shorter (3.21 Å) and four longer (3.23 Å) Rb–C bond lengths. There are two inequivalent C+0.12- sites. In the first C+0.12- site, C+0.12- is bonded in a distorted trigonal planar geometry to two equivalent Rb1+ and three C+0.12- atoms. There is one shorter (1.43 Å) and two longer (1.44 Å) C–C bond length. In the second C+0.12- site, C+0.12- is bonded in a distorted trigonal planar geometry to one Rb1+ and three C+0.12- atoms. The C–C bond length is 1.44 Å.

Materials Data on RbCuC2 by Materials Project

RbCuC2 crystallizes in the tetragonal P4/mmm space group. The structure is three-dimensional. Rb1+ is bonded to eight equivalent C1- atoms to form a mixture of face and edge-sharing RbC8 hexagonal bipyramids. All Rb–C bond lengths are 3.27 Å. Cu1+ is bonded in a linear geometry to two equivalent C1- atoms. Both Cu–C bond lengths are 1.84 Å. C1- is bonded in a distorted linear geometry to four equivalent Rb1+, one Cu1+, and one C1- atom. The C–C bond length is 1.26 Å.
