(Received 30 September 2010; accepted 20 October 2010; online 23 October 2010)

The title compound, trans-[PdCl2{PPh2(4-Me2NC6H4)}2], crystallizes with the Pd atom on a center of symmetry, resulting in a distorted trans-PdCl2P2 square-planar geometry. The Pd—P and Pd—Cl bond lengths are 2.3550 (7) and 2.2906 (7) Å, respectively. Some weak inter­actions are observed between the aromatic rings of adjacent mol­ecules, with an inter­planar distance between two π-stacked rings of 3.505 (3) Å. Intra- and intermolecular C—H⋯Cl hydrogen bonds also occur.

Comment top

Transition metal complexes containing phosphine, arsine and stibine ligands are widely being investigated in various fields of organometallic chemistry (Spessard & Miessler, 1996). As part of a systematic investigation involving complexes with the general formula trans-[MX2(L)2] (M = Pt or Pd; X = halogen, Me, Ph; L = Group 15 donor ligand), crystals of the title compound were obtained.

[PdCl2(L)2] (L = tertiary phosphine, arsine or stibine) complexes can conveniently be prepared by the substitution of 1,5-cyclooctadiene (COD) from [PdCl2(COD)]. The title compound, trans-[PdCl2{PPh2(4-Me2NC6H4)}2], crystallizes in the triclinic spacegroup P1, with the Pd atom on a center of symmetry and each pair of equivalent ligands in a mutually trans orientation. The geometry is, therefore, slightly distorted square planar and the Pd atom is not elevated out of the coordinating atom plane. All angles in the coordination polyhedron are close to the ideal value of 90°, with P—Pd—Cl = 93.84 (2) and P—Pd—Cli = 86.16 (2)°. As required by the crystallographic symmetry, the P—Pd—Pi and Cl—Pd—Cli angles are 180°. Some weak intermolecular interactions were observed and are reported in Table 1.

The title compound compares well with other closely related PdII complexes from the literature containing two chloro and two tertiary phosphine ligands in a trans geometry. The title compound, having a Pd—Cl bond length of 2.2955 (13) Å and a Pd—P bond length of 2.3398 (12) Å, fits well into the typical range for complexes of this kind. It is notable that the title compound crystallized as an unsolvated complex, as these type of PdII complexes tend to crystallize as solvates (Meijboom & Omondi, 2010).

Experimental top

Dichloro(1,5-cyclooctadiene)palladium(II), [PdCl2(COD)], was prepared according to the literature procedure of Drew & Doyle (1990). A solution of diphenyl(4-dimethylaminophenyl)phosphine (0.2 mmol) in dichloromethane (2.0 cm3) was added to a solution of [PdCl2(COD)] (0.1 mmol) in dichloromethane (3.0 cm3). Slow evaporation of the solvent gave yellow crystals of the title compound.

Refinement top

The aromatic and methyl H atoms were placed in geometrically idealized positions (C—H = 0.95–0.98) and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C) for aromatic and Uiso(H) = 1.5Ueq(C) for methyl H atoms respectively. Methyl torsion angles were refined from electron density

Experimental. The intensity data was collected on a Bruker X8 Apex II 4 K Kappa CCD diffractometer using an exposure time of 50 s/frame. A total of 604 frames were collected with a frame width of 0.5° covering up to θ = 28.28° with 99.0% completeness accomplished.

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.
