Crystal structure of μ-fluorido-bis­{(η(4)-cyclo­octa­diene)[hexa­fluorido­anti­monato(V)]platinum(II)} hexa­fluorido­anti­monate(V) hydrogen fluoride 0.75-solvate

In the complex cation of the binuclear solvated title salt, [Pt(2)F(SbF(6))(2)(C(8)H(12))(2)]SbF(6)·0.75HF, an F atom bridges the two platinum(II) atoms with a bond angle of 123.3 (2)°. The corresponding Pt—F bond lengths are in the range of other fluorine-bridged binuclear platinum(II) complexes. Two of the three SbF(6) (−) anions each coordinate with one F atom to one platinum(II) atom. Including the η(4)-bound cyclo­octa­diene (COD) ligands, the overall coordination sphere of each platinum(II) atom is square-planar. The third SbF(6) (−) anion is not bound to the complex. Hydrogen fluoride is present in the crystal structure as a solvent disordered over three positions, each with an occupancy of 0.25. F⋯F distances of 2.5512 (7), 2.6076 (8) and 3.2215 (10) Å to surrounding SbF(6) (−) anions are indicative of F—H⋯F hydrogen-bonding inter­actions although no H atoms could be localized for the disordered solvent mol­ecules. The resulting hydrogen-bonded network is three-dimensional.
