The structure described by Rb3BAs2 crystallizes in the monoclinic C2/c space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 5-coordinate geometry to one B(1) and four equivalent As(1) atoms. In the second Rb site, Rb(2) is bonded in a 7-coordinate geometry to two equivalent B(1) and five equivalent As(1) atoms. B(1) is bonded in a 7-coordinate geometry to one Rb(1), four equivalent Rb(2), and two equivalent As(1) atoms. As(1) is bonded in a 1-coordinate geometry to two equivalent Rb(1), five equivalent Rb(2), and one B(1) atom. is represented by the CIF file [CIF]
