In the complex cation of the binuclear solvated title salt, [Pt₂F(SbF₆)₂(C₈H₁₂)₂]SbF₆·0.75HF, 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 SbF₆⁻ anions each coordinate with one F atom to one platinum(II) atom. Including the η⁴-bound cyclooctadiene (COD) ligands, the overall coordination sphere of each platinum(II) atom is square-planar. The third SbF₆⁻ 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 SbF₆⁻ 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.

Keywords: crystal structure; cyclooctadiene complex; binuclear platinum complex; anhydrous hydrogen fluoride; superacid.

1. Chemical context

Platinum complexes of cyclic dienes, like cyclooctadiene (COD), are widely used in metal-organic chemistry to introduce new ligands by substitution of the diene. For instance, [Pt(CH₃)₂(COD)] is a commercially available staring material for most of the dimethyl complexes of platinum(II). Methyl ligands in platinum complexes can be protonated in superacids and eliminated as methane quantitatively. With anhydrous hydrogen fluoride (aHF), one or both methyl groups are protonated and replaced by a fluoride ion, but the resulting products cannot be crystallized because the formed fluoride ion does not sufficiently stabilizes the platinum complexes. With larger counter-anions like BF₄⁻, AsF₆⁻ or SbF₆⁻, stable crystalline complexes can be formed and isolated (Friedemann & Seppelt, 2013 ).

One methyl group of [Pt(CH₃)₂(COD)] reacts with aHF at low temperature under formation of methane; the second methyl group can be eliminated by the addition of antimony pentafluoride. The resulting dissolved complex is stable at room temperature and can be crystallized by cooling to 200 K. The formed title compound [Pt₂(COD)₂F(SbF₆)₂]SbF₆·0.75HF dissolves unreacted only in aHF or acetonitrile. With other organic solvents, a reaction takes place to form black undefined oils; with chlorinated solvents chlorido-platinum complexes are formed instead.

2. Structural commentary

Each of the two independent platinum(II) atoms is surrounded by one COD ligand in a double π-coordination, one fluorine atom of a SbF₆⁻ anion and one bridging fluorine atom, resulting in a slightly distorted square-planar coordination sphere (Fig. 1). The fluorine atom F19 bridges the two platinum(II) atoms with a bond angle of 123.3 (2)°. The corresponding Pt—F bond lengths [2.085 (4) Å and 2.065 (4) Å] are in the range of other fluorine-bridged binuclear platinum complexes [Pt—F 2.030 (9)–2.083 (10) Å; Friedemann & Seppelt, 2013) and somewhat longer than in non-bridging complexes like [PtF₂(PPh₃)₂] [Pt—F = 1.999 (2) and 2.016 (2) Å; Yahav et al., 2005 ). The two PtF₂ planes are twisted by 69.8 (3)°. The third SbF₆⁻ anion is not bonded to the complex. The COD ligands are bonded much stronger to the platinum(II) atoms than in the starting compound [Pt(CH₃)₂(COD)] (Smith et al., 2000 ). This leads to shorter Pt—C bond lengths by up to 0.1 Å and an elongation of the olefinic bonds. The bite angles of the chelating ligands [88.85 (1)° at Pt1, 89.05 (1)° at Pt2] are close to the ideal 90° of a square-planar Pt²⁺ complex.

3. Supramolecular features

The [Pt₂(COD)₂F(SbF₆)₂] cations and SbF₆ anions are packed in such a way that voids are generated that are filled with disordered HF solvent molecules (F21, F221 and F222). The shortest distances of these atoms to fluorine atoms of the surrounding SbF₆⁻ anions [F221⋯F18 2.5512 (7), F222⋯F18 2.6076 (8) and F21⋯F5 3.2215 (10) Å] are in the typical range of F—H⋯F donor acceptor distances, marked in Fig. 1 with dashed lines. The packing of the molecular entities in the crystal structure is shown in Fig. 2.

4. Synthesis and crystallization

[Pt(CH₃)₂(COD)] (40 mg, 0.12 mmol) and antimony(V) fluoride (80 mg, 0.36 mmol) were filled separated in a two chamber PFA tube. Anhydrous HF (0.5 ml) was condensed on it at 77 K. By heating to 200 K and mixing, a gas and a yellow solid were formed. The solid dissolved at room temperature under a second gas formation to a give clear yellow solution. The gas was removed and the sealed tube was slowly cooled to 200 K to form yellow single crystals of the title compound. NMR in aHF at room temperature: ¹H d: 2.02 (m, br, 4H), 2.61 (m, br, 4H), 5.73 (s, 4H, ²J_H,Pt = 95 Hz). NMR in CD₃CN at room temperature: ¹H d: 2.44 (m, br, 4H), 2.75 (m, br, 4H), 6.17 (s, 4H, ²J_H,Pt = 67 Hz); ¹⁹F d: 122 (m, br); ¹³C{¹H} d: 31.4 (s), 109.9 (¹J_C,Pt = 162 Hz); ¹⁹⁵Pt{¹⁹F} d: −3424 (s).

5. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 1. H atom positions of the COD ligand were refined with calculated positions in a riding model with C—H = 0.97 and 0.98 Å and U_iso(H) = 1.2U_eq(C). Atoms F21, F221 and F222 that are associated with the hydrogen fluoride solvent are disordered and were refined isotropically. Their occupation factors were fixed to 0.25 for each of these atoms which showed the best results in terms of reliability factors and U_iso values. Hydrogen atoms bound to the disordered solvent F atoms could not be detected and were consequently not considered in the final model. Some F atoms of the SbF₆⁻ anions exhibited somewhat elongated ellipsoids. Since consideration of a split atom model had a negative effect (parts of these atoms could then only be refined isotropically), all F atoms of the SbF₆⁻ anions were not refined as being disordered.

Special details top

Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds involving l.s. planes.
