Solvothermal Synthesis and Crystal Structure of a Novel Inorganic-Organic Hybrid Material, Fe₂O(OH)(C₅H₄NCOO)SO₄

A novel inorganic-organic hybrid material, Fe₂O(OH)(C₅H₄-NCOO)SO₄ was synthesized via solvothermal route using a reaction of FeCl₃ ·6H₂O, KCNS, and 4-cyanopyridne in aqueous solution of H₂O₂ and ethanol at 130 °C for 3 d. The compound crystallized in monoclinic space group P2₁, with cell parameters a=0.73850(15) nm, b = 0.65100(13) mn, c = 1.0546(2) nm, β = 90.36(3)°, V = 0.50700(18) nm³ and Z = 2. The structure is constructed with inorganic layered [Fe₂O(OH) SO₄]⁺ cations linked by organic (C₅H₄NCOO)⁻ anions. The compound is thermally stable up to approximately 240 °C.
