(Ferrocenylthiophosphonato-κS)(triphenylphosphane-κP)gold(I) dichloromethane monosolvate

H. van der Walt, A. Muller, R. J. Staples and W. E. Van Zyl

In the title compound, [AuFe(C₅H₅)(C₅H₅O₂PS)(C₁₈H₁₅P)]·CH₂Cl₂, the two-coordinate gold(I) atom shows a slightly distorted linear arrangement, with a P—Au—S bond angle of 176.81 (6)°. The difference in P=O and P—O(H) bond lengths, which are 1.503 (6) and 1.541 (5) Å, respectively, implies there is apparently no delocalization between the P—O bonds, and the proton appears to be localized on one O atom only. In the crystal structure, intermolecular O—H

O hydrogen bonds link dinuclear molecules into chains propagated in the [010] direction. The dichloromethane solvent molecule was disordered between two positions in a 0.63 (3):0.37 (3) ratio.

Comment top

The dithiophosphonato dianion salt, (NH₄)₂[S₂P(Fc)OCH₂CH₂O(Fc)PS₂] (Fc = ferrocenyl) was used in this study. It was obtained from the reaction between the dimer [PS₂(Fc)]₂ (Foreman et al., 1996) and ethanediol, which formed a diacid. The diacid could be readily deprotonated by ammonia gas. The salt was then reacted with [Au(PPh₃)Cl] to yield the complex [(PPh₃)AuS₂(Fc)P(OC₂H₄O)P(Fc)S₂Au(PPh₃)] (I). The complex was fully characterized spectroscopically (see Experimental). During work-up for crystal growth, however, the ligand became oxidized, presumably as a result of water present in the solvent dichloromethane. This resulted in substitution of a terminal P═S bond with a P═O bond, a reaction that can readily occur with oxophilic phosphorus(V) in the presence of moisture. Additionally, it resulted in C—O bond cleavage to be replaced with H—O bond formation. A precise mechanism for the reaction is not proposed. The title compound I (see Fig 1) crystalizes in the P2₁/c space group with molecules lying on general positions in the unit cell. All geometrical data for the compound are within the normal limits (Allen, 2002). In the crystal packing, there is a hydrogen-bonding network along the b axis between the P═ O···H—O—P moieties (see Fig 2 and Table 1).

Experimental top

The complex (I) was obtained as an oxidized product. The initial reaction was between the (NH₄)₂[S₂P(Fc)OCH₂CH₂O(Fc)PS₂] salt (Fc = ferrocenyl) (0.122 g, 0.206 mmol) and [Au(PPh₃)Cl] (0.200 g, 0.413 mmol) in a THF solution. The NH₄Cl was filtered off and the filtrate solvent removed under reduced pressure yielding a yellow colored powder. Yield: 0.127 g (41%). M.p.: 128°C. ¹H-NMR (CDCl₃) δ: 7.54 – 7.45 (m, 30H, PPh₃); 4.65 – 4.22 (d, 4H, Fc); 4.53 – 4.50 (d, 4H, Fc); 4.30 (s, 10H, Fc); 4.36 – 4.31 (t, 2H, CH₂); 3.99 – 3.93 (m, 2H, CH₂). ³¹P-NMR δ: 106.14 and 106.03 (d, 2P, P—S); 37.82 (s, 2P, PPh₃). ESI-MS: m/z 1539 (95%) for [(PPh₃)AuS₂(Fc)P(OC₂H₄O)P(Fc)S₂Au(PPh₃)].

Special details top

Experimental. The intensity data was collected on a Bruker CCD based diffractometer equipped with an Oxford Cryostream low-temperature apparatus operating at 173 K diffractometer using an exposure time of 30 s/frame. A total of 1276 frames were collected with a frame width of 0.5° covering up to θ = 28.63% with 86.5% completeness accomplished. Due to decomposition and the weak diffracting nature of the title compound, refinement of data was restricted to θ = 25.0% to reach a completeness of 95.5%.

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

Refinement. Refinement of F² against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F², conventional R-factors R are based on F, with F set to zero for negative F². The threshold expression of F² > σ(F²) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F² are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
