Materials Data on RbAgC2 by Materials Project
RbAgC2 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 3.28 Å. Ag1+ is bonded in a linear geometry to two equivalent C1- atoms. Both Ag–C bond lengths are 2.04 Å. C1- is bonded in a distorted linear geometry to four equivalent Rb1+, one Ag1+, and one C1- atom. The C–C bond length is 1.25 Å.
