Rb2CaSb2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Rb2CaSb2 cluster. Rb(1) is bonded in a single-bond geometry to one Sb(1) atom. Ca(1) is bonded in a linear geometry to two equivalent Sb(1) atoms. Sb(1) is bonded in a linear geometry to one Rb(1) and one Ca(1) atom.
