The material described by Rb2CaAs2 crystallizes in the tetragonal P4/mmm space group. The structure is zero-dimensional and consists of one Rb2CaAs2 cluster. Rb(1) is bonded in a single-bond geometry to one As(1) atom. Ca(1) is bonded in a linear geometry to two equivalent As(1) atoms. As(1) is bonded in a linear geometry to one Rb(1) and one Ca(1) atom. is represented by the CIF card [CIF]
