W2ReFe crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two W2ReFe clusters. There are two inequivalent W sites. In the first W site, W(1) is bonded in a single-bond geometry to one W(2) atom. The W(1)-W(2) bond length is 0.22 Å. In the second W site, W(2) is bonded in a distorted linear geometry to one W(1) and one Fe(1) atom. The W(2)-Fe(1) bond length is 2.04 Å. Re(1) is bonded in a distorted single-bond geometry to one Fe(1) atom. The Re(1)-Fe(1) bond length is 2.34 Å. Fe(1) is bonded in a distorted single-bond geometry to one W(2) and one Re(1) atom.
