Fe Fe Co W
FeWFeCo crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two FeCo clusters and two FeW clusters. In each FeCo cluster, Fe(2) is bonded in a single-bond geometry to one Co(1) atom. The Fe(2)-Co(1) bond length is 1.21 Å. Co(1) is bonded in a single-bond geometry to one Fe(2) atom. In each FeW cluster, W(1) is bonded in a single-bond geometry to one Fe(1) atom. The W(1)-Fe(1) bond length is 2.01 Å. Fe(1) is bonded in a distorted single-bond geometry to one W(1) atom.
