The structure described by RbAg3Se2 crystallizes in the monoclinic C2/m space group. Rb(1) is bonded in a 7-coordinate geometry to three equivalent Se(2) and four equivalent Se(1) atoms. There are three inequivalent Ag sites. In the first Ag site, Ag(1) is bonded in a distorted bent 120 degrees geometry to one Se(1) and three equivalent Se(2) atoms. In the second Ag site, Ag(2) is bonded in a distorted trigonal planar geometry to one Se(2) and two equivalent Se(1) atoms. In the third Ag site, Ag(3) is bonded in a distorted trigonal non-coplanar geometry to one Se(1) and two equivalent Se(2) atoms. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a 8-coordinate geometry to four equivalent Rb(1), one Ag(1), one Ag(3), and two equivalent Ag(2) atoms. In the second Se site, Se(2) is bonded in a 9-coordinate geometry to three equivalent Rb(1), one Ag(2), two equivalent Ag(3), and three equivalent Ag(1) atoms. is represented by the CIF card [CIF]
