The material structure described by Rb3Sb is Sodium arsenide structured and crystallizes in the hexagonal P6_3/mmc space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a trigonal planar geometry to three equivalent Sb(1) atoms. In the second Rb site, Rb(2) is bonded in a 1-coordinate geometry to four equivalent Sb(1) atoms. Sb(1) is bonded in a 11-coordinate geometry to three equivalent Rb(1) and eight equivalent Rb(2) atoms. is represented by the CIF card [CIF]
