Abstract top

The title compound, [Pd2Cl2(C6H5S)2(C18H15P)2]·2CHCl3, contains a centrosymmetric dinuclear palladium complex with the PdII cation in a slightly distorted square-planar coordination environment. The PdII cations are bridged by the S atoms of two benzenethiolate ligands with different Pd-S distances [2.2970 (11) and 2.3676 (11) Å]. The coordination of the metal atom is completed by a chloride anion [2.3383 (11) Å] and a triphenylphosphane ligand [2.2787 (11) Å]. Weak C-H...Cl interactions are present between complex molecules and the CHCl3 solvent molecule. The latter is disordered over two positions in a 0.792 (8):0.208 (8) ratio. The crystal under investigation was found to be twinned by nonmerohedry, with a fraction of 73.4 (1)% for the major twin component.

Comment top

Palladium is a transition metal well known for synthetic chemists. Thus, palladium complexes have been extensively studied and have had important applications as catalysts in a plethora of organic transformations, biological applications, material science etc. As catalysts, palladium complexes have shown high efficiency in different protocols of cross-coupling reactions for the construction of C—C bonds, e.g. through Heck reaction (Yin & Liebscher, 2007), Suzuki–Miyaura coupling (Frisch & Beller, 2005), Negishi reaction (Knochel & Singer, 1993), as well as for the formation of C-heteroatom highlighted via Buchwal–Hartwig reaction (Surry & Buchwald, 2008). In this context we report here the structure of the title compound, trans-[PdCl(C6H5S)(C18H15P)]2.2CHCl3, (I).

The structure of (I) contains a centrosymmetric dimeric PdII complex with the PdII atom within a slightly distorted square-planar coordination environment (Fig. 1). The two PdII atoms are bridged by two –SC6H5 ligands, and the coordination environment is completed by one Cl- and one PPh3 ligand. The asymmetric unit is composed of half of the complex and one disordered CHCl3 solvent molecule; the full molecule is completed by application of inversion symmetry.

The two bridging –SC6H5 ligands exhibit different Pd1—S1 bond lengths, 2.2970 (11) and 2.3676 (11) Å; these distances are comparable to those found in the structure of the related compound [Pd(PPh3)(SC6F5)(µ-SC6F5)]2 (Estudiante-Negrete et al., 2007). The Pd1—P1 and Pd1—Cl1 bonds lengths are 2.2787 (11) and 2.3383 (11) Å, respectively. The Cl- and the PPh3 ligands are arranged in a mutually trans conformation.

The complex molecules are packed in rows parallel to [010]. The structure is stabilized by weak C—H···Cl hydrogen-bonding interactions between complex molecules and interstitial solvent molecules (Fig. 2).

Experimental top

To a suspension of PdCl2 (0.078 g, 0.442 mmol) and Na2CO3 (0.050 g, 0.047 mmol) in 15 ml of toluene a solution of 1-ethenyl-[(phenylsulfanyl)methyl]-benzene (isomeric mix 60:40), 1-ethenyl-3-[(phenylsulfanyl)methyl]-benzene and 1-ethenyl-4-[(phenylsulfanyl)methyl]-benzene) (0.100 g, 0.442 mmol) in 5 ml of toluene was added. The resulting mixture was set to reflux for 4 h. After this time the reaction mixture was allowed to cool down to room temperature and filtered. The solid residue was further washed twice with CHCl3 (5 ml) attaining a yellow solid. This solid was further treated with PPh3 (0.232 g, 0.884 mmol) in 15 ml of CHCl3. The reaction mixture was stirred until all solid was dissolved and the resulting solution was filtered through a short plug of Celite. The filtrate was left to evaporate at room temperature yielding yellow crystals of (I) suitable for X-ray diffraction analysis.

Refinement top

H atoms were included in calculated positions (C—H = 0.93 Å for aromatic H) and refined using a riding model with Uiso(H) = 1.2 Ueq of the carrier atoms. In the refinement five reflections, (1 16 4), (-11 4 5), (-2 15 8), (8 11 5) and (-9 12 5), were considered as disagreeable and were omitted. The CHCl3 solvent is disordered over two sets of sites in a 0.792 (8):0.208 (8) ratio. Twinning by non-merohedy was detected in the cell determination and two orientation matrices were determined. The data were then processed and corrected for absorption effects with the TWINABS program (Bruker, 2007). The refinement of the BASF parameter was 26.6 (1)%, indicating a fraction of 73.4 (1)% for the major twin component.

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. Refined as a 2-component twin.
