The material described by Rb2VAgSe4 crystallizes in the orthorhombic Fddd space group. Rb(1) is bonded in a 8-coordinate geometry to eight equivalent Se(1) atoms. V(1) is bonded in a tetrahedral geometry to four equivalent Se(1) atoms. Ag(1) is bonded in a 4-coordinate geometry to four equivalent Se(1) atoms. Se(1) is bonded in a 6-coordinate geometry to four equivalent Rb(1), one V(1), and one Ag(1) atom. is represented by the CIF card [CIF]
