Comment
=======

Recently, we have shown that the degradation of Cl~3~SiSiCl~3~ in the presence of donors, such as amines N*R*~3~ (*R* = Me, Et) and phosphanes P*R*~3~ (*R* = *t*Bu) and the isoelectronic silanide \[Si*t*Bu~3~\]^-^ (Lerner, 2005), in the first step gives dichlorsilylene SiCl~2~ and ultimately produces the perchlorinated neopentasilane Si(SiCl~3~)~4~ and in the case of the silanide the silatetrahedrane (*t*Bu~3~Si)~4~Si~4~, respectively (Meyer-Wegner *et al.*,  2009, 2011).  Moreover, we verified that the donor-induced degradation of Cl~3~SiSiCl~3~ 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 Cl~3~SiSiCl~3~ and \[Pd(PPh~3~)~4~\].  However, the reaction of Cl~3~SiSiCl~3~ with \[Pd(PPh~3~)~4~\] gives exclusively \[PdCl~2~(PPh~3~)~2~\] (Fig.  1).  Apparently no dichlorsilylene transition metal complex was formed thereby.  Single crystals composed of one have molecule of benzene and one molecule of \[PdCl~2~(PPh~3~)~2~\] 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 PPh~3~ 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 {#experimental}
============

Pd(PPh~3~)~4~ (0.19 g, 0.16 mmol) was suspended in benzene (5 ml) and then treated with one equivalent of Si~2~Cl~6~ (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. 

Refinement {#refinement}
==========

H atoms were refined using a riding model, with C---H = 0.95 Å and with *U*~iso~(H) = 1.2*U*~eq~(C).  The C---C distances in the solvent benzene molecule were restrained to 1.39 (1) Å.

  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 *F*^2^ against ALL reflections.  The weighted *R*-factor *wR* and goodness of fit *S* are based on *F*^2^, conventional *R*-factors *R* are based on *F*, with *F* set to zero for negative *F*^2^. The threshold expression of *F*^2^ \> σ(*F*^2^) is used only for calculating *R*-factors(gt) *etc*.  and is not relevant to the choice of reflections for refinement. * R*-factors based on *F*^2^ are statistically about twice as large as those based on *F*, and *R*- factors based on ALL data will be even larger.
