W2Re crystallizes in the triclinic P1 space group. There are eight inequivalent W sites. In the first W site, W(1) is bonded in a 2-coordinate geometry to one W(7) and one Re(2) atom. The W(1)-W(7) bond length is 1.33 Å. The W(1)-Re(2) bond length is 1.74 Å. In the second W site, W(2) is bonded in a 2-coordinate geometry to one W(7) and one Re(1) atom. The W(2)-W(7) bond length is 1.33 Å. The W(2)-Re(1) bond length is 1.74 Å. In the third W site, W(3) is bonded in a distorted single-bond geometry to one W(6) and one Re(3) atom. The W(3)-W(6) bond length is 1.32 Å. The W(3)-Re(3) bond length is 3.22 Å. In the fourth W site, W(4) is bonded in a 1-coordinate geometry to one Re(1) and one Re(3) atom. The W(4)-Re(1) bond length is 1.69 Å. The W(4)-Re(3) bond length is 2.78 Å. In the fifth W site, W(5) is bonded in a 2-coordinate geometry to one W(6) and one W(8) atom. The W(5)-W(6) bond length is 1.63 Å. The W(5)-W(8) bond length is 1.32 Å. In the sixth W site, W(6) is bonded in a 2-coordinate geometry to one W(3), one W(5), and one Re(3) atom. The W(6)-Re(3) bond length is 3.64 Å. In the seventh W site, W(7) is bonded in a 3-coordinate geometry to one W(1), one W(2), and one Re(4) atom. The W(7)-Re(4) bond length is 1.69 Å. In the eighth W site, W(8) is bonded in a 1-coordinate geometry to one W(5) atom. There are four inequivalent Re sites. In the first Re site, Re(1) is bonded in a 2-coordinate geometry to one W(2), one W(4), and two equivalent Re(3) atoms. There is one shorter (2.89 Å) and one longer (3.33 Å) Re(1)-Re(3) bond length. In the second Re site, Re(2) is bonded in a single-bond geometry to one W(1) and two equivalent Re(3) atoms. There is one shorter (2.92 Å) and one longer (3.37 Å) Re(2)-Re(3) bond length. In the third Re site, Re(3) is bonded in a 8-coordinate geometry to one W(3), one W(4), one W(6), one Re(4), two equivalent Re(1), and two equivalent Re(2) atoms. The Re(3)-Re(4) bond length is 3.29 Å. In the fourth Re site, Re(4) is bonded in a distorted single-bond geometry to one W(7) and one Re(3) atom.
