W2RhBr crystallizes in the triclinic P1 space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 1-coordinate geometry to one Rh(1) and one Br(1) atom. The W(1)-Rh(1) bond length is 1.09 Å. The W(1)-Br(1) bond length is 3.39 Å. In the second W site, W(2) is bonded in a 2-coordinate geometry to one Rh(1) and two equivalent Br(1) atoms. The W(2)-Rh(1) bond length is 2.47 Å. There is one shorter (2.65 Å) and one longer (3.10 Å) W(2)-Br(1) bond length. Rh(1) is bonded in a 1-coordinate geometry to one W(1) and one W(2) atom. Br(1) is bonded in a 7-coordinate geometry to one W(1), two equivalent W(2), and four equivalent Br(1) atoms. All Br(1)-Br(1) bond lengths are 2.91 Å.
