The structure described by Rb3Re is alpha bismuth trifluoride structured and crystallizes in the tetragonal I4/mmm space group. There are two inequivalent Rb sites. In the first Rb site, Rb(1) is bonded in a 4-coordinate geometry to four equivalent Rb(2) and four equivalent Re(1) atoms. In the second Rb site, Rb(2) is bonded to eight equivalent Rb(1) and four equivalent Re(1) atoms to form distorted RbRb8Re4 cuboctahedra that share corners with four equivalent Rb(2)Rb8Re4 cuboctahedra, corners with eight equivalent Re(1)Rb12 cuboctahedra, edges with eight equivalent Rb(2)Rb8Re4 cuboctahedra, faces with four equivalent Rb(2)Rb8Re4 cuboctahedra, and faces with six equivalent Re(1)Rb12 cuboctahedra. Re(1) is bonded to four equivalent Rb(2) and eight equivalent Rb(1) atoms to form ReRb12 cuboctahedra that share corners with four equivalent Re(1)Rb12 cuboctahedra, corners with eight equivalent Rb(2)Rb8Re4 cuboctahedra, edges with eight equivalent Re(1)Rb12 cuboctahedra, faces with four equivalent Re(1)Rb12 cuboctahedra, and faces with six equivalent Rb(2)Rb8Re4 cuboctahedra. is represented by the CIF card [CIF]
