Solvothermal Synthesis, Crystal Structures, and Magnetic Properties of Two Organically Templated Iron Sulfates with Chain Structures.

Two new one-dimensional (1D) organically templated iron(III) sulfates [C2NH8]3 [Fe3(μ3-O)2(SO4)4] (1) and [C2N2H10][C2NH7]0.5[FeF(SO4)2] (2) were synthesized under solvothermal conditions and characterized by single-crystal X-ray diffraction, powder X-ray diffraction (XRD), FT-IR spectroscopy, elemental analyses, ICP analyses, and thermogravimetric analyses. Single-crystal structure analysis reveals that both compounds show linear-chain structures, involving FeO6 (FeF2O4) octahedra and SO4 tetrahedra. The magnetic properties of the two compounds have also been investigated.
