✦ Synopsis
Silver(II) Fluorosulfate: A Thermally Fragile Ferromagnetic Derivative of Divalent Silver in an Oxa-Ligand Environment. -Two novel routes to synthesize Ag(SO3F)2 are reported: methathesis reaction between Ag(SbF6)2 and KSO3F in anhydrous HF (-84→+25 °C; ≈100% yield) and reaction of AgF2 with HSO3F (25-50 °C, 4 d). Single crystals of the compound instantly decompose to Ag I SO3F and, therefore, the structure is solved from powder XRD data (monoclinic, space group P2 1 , Z = 4). The structure contains puckered [Ag(SO3F)2] sheets. Two oxygen atoms of the fluorosulfate anions are involved in bonds within the sheet and the third oxygen atom serves as a linker to the adjacent sheet. Ag(SO3F)2 is further characterized by IR and Raman spectroscopy, thermal analysis, magnetic measurements, and DFT calculations. -(MALINOWSKI, P.
