(Received 21 March 2012; accepted 22 March 2012; online 31 March 2012)

The title complex, [PdCl₂(C₁₈H₁₅P)₂]·0.5C₆H₆, has the Pd^II ion in a square-planar coordination mode (r.m.s. deviation for Pd, P and Cl atoms = 0.024 Å) with the PPh₃ and Cl ligands mutually trans. The benzene solvent molecule is located about a crystallographic inversion centre. The title complex is isostructural with trans-dichloridobis(triphenylphosphane)palladium(II) 1,4-dichlorobenzene sesquisolvate [Kitano et al. (1983 ). Acta Cryst. C39, 1015–1017].

Comment top

Recently, we have shown that the degradation of Cl₃SiSiCl₃ in the presence of donors, such as amines NR₃ (R = Me, Et) and phosphanes PR₃ (R = tBu) and the isoelectronic silanide [SitBu₃]^- (Lerner, 2005), in the first step gives dichlorsilylene SiCl₂ and ultimately produces the perchlorinated neopentasilane Si(SiCl₃)₄ and in the case of the silanide the silatetrahedrane (tBu₃Si)₄Si₄, respectively (Meyer-Wegner et al., 2009, 2011). Moreover, we verified that the donor-induced degradation of Cl₃SiSiCl₃ in the presence of the silylene trapping agent 2,3-dimethyl-1,3-butadiene gives the [4 + 1] cycloadduct (Meyer-Wegner et al., 2011). We are currently interested in dichlorsilylene transition metal complexes. To this end, we thought that such complexes can be prepared using the reaction between Cl₃SiSiCl₃ and [Pd(PPh₃)₄]. However, the reaction of Cl₃SiSiCl₃ with [Pd(PPh₃)₄] gives exclusively [PdCl₂(PPh₃)₂] (Fig. 1). Apparently no dichlorsilylene transition metal complex was formed thereby. Single crystals composed of one have molecule of benzene and one molecule of [PdCl₂(PPh₃)₂] could be isolated from the reaction solution.

The title complex (Fig. 2) has the Pd centre in a quadratic planar (r.m.s. deviation for Pd, P and Cl atoms: 0.024 Å) coordination mode with the PPh₃ and Cl ligands mutually trans. The solvent benzene molecule is located about a crystallographic inversion centre. The title compound is isomorphous with trans-dichlorido-bis(triphenylphosphane)palladium(II) sesqui(p-dichlorobenzene) (Kitano et al., 1983). The packing diagram (Fig. 3) shows how the benzene molecules fill the empty space between the complexes. There are no unusual features.

Experimental top

Pd(PPh₃)₄ (0.19 g, 0.16 mmol) was suspended in benzene (5 ml) and then treated with one equivalent of Si₂Cl₆ (0.028 ml, 44 mg, 0.16 mmol) in benzene (0.5 ml) at ambient temperature. The solution immediately became clear and turned from yellow to dark red. Crystals of the title compound were obtained by slow evaporation of the solvent at ambient temperature.

Special details top

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.
