The crystal structure described by FeOCl4FeCl2(O)4 is Indium-like structured and crystallizes in the orthorhombic Pca2_1 space group. The structure is zero-dimensional and consists of four dichloroiron;tetrahydrate molecules and four FeOCl4 clusters. In each FeOCl4 cluster, Fe(1) is bonded in a tetrahedral geometry to one Cl(1), one Cl(2), one Cl(3), and one Cl(4) atom. O(1) is bonded in a water-like geometry to one Cl(1) and one Cl(2) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a distorted L-shaped geometry to one Fe(1) and one O(1) atom. In the second Cl site, Cl(2) is bonded in a distorted L-shaped geometry to one Fe(1) and one O(1) atom. In the third Cl site, Cl(3) is bonded in a single-bond geometry to one Fe(1) atom. In the fourth Cl site, Cl(4) is bonded in a single-bond geometry to one Fe(1) atom. is represented by the CIF file [CIF]
