K3NaFeCl6 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight equivalent Cl1- atoms. There are a spread of K–Cl bond distances ranging from 3.19–3.39 Å. Na1+ is bonded in a 6-coordinate geometry to six equivalent Cl1- atoms. All Na–Cl bond lengths are 2.84 Å. Fe2+ is bonded in an octahedral geometry to six equivalent Cl1- atoms. All Fe–Cl bond lengths are 2.51 Å. Cl1- is bonded to four equivalent K1+, one Na1+, and one Fe2+ atom to form a mixture of distorted corner, edge, and face-sharing ClK4NaFe octahedra. The corner-sharing octahedra tilt angles range from 0–62°.
