K2FeH2OCl5 crystallizes in the orthorhombic Pnma space group. K(1) is bonded in a 8-coordinate geometry to two equivalent Cl(1), two equivalent Cl(2), two equivalent Cl(3), and two equivalent Cl(4) atoms. Fe(1) is bonded in an octahedral geometry to one O(1), one Cl(1), one Cl(2), one Cl(3), and two equivalent Cl(4) atoms. H(1) is bonded in a single-bond geometry to one O(1) atom. O(1) is bonded in a distorted trigonal planar geometry to one Fe(1) and two equivalent H(1) atoms. There are four inequivalent Cl sites. In the first Cl site, Cl(4) is bonded in a distorted single-bond geometry to two equivalent K(1) and one Fe(1) atom. In the second Cl site, Cl(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one Fe(1) atom. In the third Cl site, Cl(2) is bonded to four equivalent K(1) and one Fe(1) atom to form a mixture of distorted face, corner, and edge-sharing ClK4Fe square pyramids. In the fourth Cl site, Cl(3) is bonded to four equivalent K(1) and one Fe(1) atom to form a mixture of distorted face, corner, and edge-sharing ClK4Fe square pyramids.
