FeCl2(H2O)4 is Indium-like structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four iron dichloride tetrahydrate molecules. Fe(1) is bonded in an octahedral geometry to one O(1), one O(2), one O(5), one O(6), one Cl(1), and one Cl(2) atom. There are six inequivalent H sites. In the first H site, H(1,2) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(5,6) is bonded in a single-bond geometry to one O(2) atom. In the third H site, H(10) is bonded in a single-bond geometry to one O(6) atom. In the fourth H site, H(9) is bonded in a single-bond geometry to one O(5) atom. In the fifth H site, H(13) is bonded in a single-bond geometry to one O(5) atom. In the sixth H site, H(14) is bonded in a single-bond geometry to one O(6) atom. There are four inequivalent O sites.
