The asymmetric unit of the title compound, [PtCl₂(C₁₉H₁₇P)₂]₂·3CH₂Cl₂, contains two complex molecules and three dichloromethane solvent molecules, two of which are disordered over various positions. The Pt^II complexes reveal a slightly distorted square-planar geometry with average Pt—P and Pt—Cl bond lengthss of 2.252 (8) and 2.363 (8) Å, respectively, and average P—Pt—P and Cl—Pt—Cl angles of 99.17 (8) and 87.1 (7)°, respectively.

Comment top

Transition metal complexes containing phosphane, 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 cis/trans-[MX₂(L)₂] (M = Pt or Pd; X = halogen, Me, Ph; L = group 15 donor ligand), crystals of the title compound, were obtained.

[PtCl₂(L)₂] (L = tertiary phosphane, arsine or stibine) complexes can conveniently be prepared by the substitution of 1,5-cyclooctadiene (COD) from [PtCl₂(COD)]. The title compound, cis-[PtCl₂(PBzPh₂)₂], revals distorted square-planar coordination (Fig. 1 and Table 1) and the Pt atom is slightly elevated out of the coordinating atom plane. All bond angles in the coordination environment of the metal centre deviate significantly from what would be expected for a square-planar geometry. The wide P1—Pt1—P2 angle of 99.2 (2)° and the narrow Cl1—Pt1—Cl2 angle of 87.6 (2)° are a reflection of the steric impact of the two bulky phosphane ligands being in close proximity.

The title compound compares well with other closely related Pt^II complexes from the literature containing two chloro and two tertiary phosphane ligands in a cis geometry. The average Pt—Cl and Pt—P bond distances of 2.2519 (6) and 2.3627 (6) Å, respectively, fit well into the typical range for complexes of this kind. The title compound crystallises as a solvated complex which is common for these type of Pt^II complexes (Johansson et al., 2002). In addition, intramolecular π-stacking between phenyl rings, with distances of 3.5252 (3) and 3.5333 (2) Å, are observed (Fig. 2).

Experimental top

Dichloro(1,5-cyclooctadiene)platinum(II), [PtCl₂(COD)], was prepared according to the literature procedure of Drew & Doyle (1990). A solution of benzyldiphenylphosphane (55.3 mg, 0.2 mmol) in dichloromethane (2 mL) was added to a solution of [PtCl₂(COD)] (28.6 mg, 0.1 mmol) in dichloromethane (3 mL). The initial colourless solution turned light-yellow and immediately colourless. Slow evaporation of the solvent gave colourless crystals of the title compound.

Special details top

Experimental. The intensity data was collected on a Bruker Apex DUO 4 K CCD diffractometer using an exposure time of 20 s/frame. A total of 3086 frames were collected with a frame width of 0.5° covering up to θ = 28.42° with 99.3% 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.

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.

Highly disordered solvate molecules were observed, resulting in residual electron density around the Cl atoms. Different disordered models, however, resulted in unstable refinement cycles.
