FeInSb2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two FeInSb2 clusters. Fe(1) is bonded in a distorted single-bond geometry to one In(1) and two equivalent Sb(1) atoms. The Fe(1)-In(1) bond length is 0.16 Å. Both Fe(1)-Sb(1) bond lengths are 1.89 Å. In(1) is bonded in a single-bond geometry to one Fe(1) atom. Sb(1) is bonded in a distorted single-bond geometry to one Fe(1) atom.
