The crystal structure described by RbCu4Se3 crystallizes in the tetragonal P4/mmm space group. Rb(1) is bonded in a body-centered cubic geometry to eight equivalent Se(2) atoms. Cu(1) is bonded to two equivalent Se(1) and two equivalent Se(2) atoms to form a mixture of corner and edge-sharing CuSe4 tetrahedra. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a body-centered cubic geometry to eight equivalent Cu(1) atoms. In the second Se site, Se(2) is bonded in a 8-coordinate geometry to four equivalent Rb(1) and four equivalent Cu(1) atoms. is represented by the CIF card [CIF]
