Abstract: | On the Reaction of HCl with HF/SbF5 and the Crystal Structure of SbCl3F2 The reaction of HCl in HF/SbF5 solution at ?78°C yields H2F+SbClF5?. At ?40°C formation of SbCl3F2 was observed, which crystallizes in the tetragonal space group I-4 with a = 1 281.6(5) pm, c = 758.1(6) pm with 8 formula units per unit cell. The structure contains cis-fluorine-bridged tetramers, in which Sb has a distorted octahedral coordination. |
