The structure described by Rb2CoSe2 crystallizes in the orthorhombic Ibam space group. Rb(1) is bonded in a 8-coordinate geometry to two equivalent Co(1) and six equivalent Se(1) atoms. Co(1) is bonded to four equivalent Rb(1) and four equivalent Se(1) atoms to form distorted face-sharing CoRb4Se4 tetrahedra. Se(1) is bonded in a 8-coordinate geometry to six equivalent Rb(1) and two equivalent Co(1) atoms. is represented by the CIF card [CIF]
