RbAuC2 crystallizes in the tetragonal P4/mmm space group. Rb(1) is bonded to eight equivalent C(1) atoms to form a mixture of edge and face-sharing RbC8 hexagonal bipyramids. Au(1) is bonded in a linear geometry to two equivalent C(1) atoms. C(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one Au(1), and one C(1) atom.
RbAuC2 crystallizes in the tetragonal P4/mmm space group. Rb(1) is bonded to eight equivalent C(1) atoms to form a mixture of edge and face-sharing RbC8 hexagonal bipyramids.
