| Abstract: | Ferric sulfate trihydrate has been synthesized at 403 K under hydrothermal conditions. The structure consists of quadruple chains of [Fe2(SO4)3(H2O)3] parallel to [010]. Each quadruple chain is composed of equal proportions of FeO4(H2O)2 octahedra and FeO5(H2O) octahedra sharing corners with SO4 tetrahedra. The chains are joined to each other by hydrogen bonds. This compound is a new hydration state of Fe2(SO4)3·nH2O; minerals with n = 0, 5, 7.25–7.75, 9 and 11 are found in nature. |
