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

[PtCl₂(L)₂] (L = tertiary phosphine, arsine or stibine) complexes can conveniently be prepared by the substitution of 1,5-cyclooctadiene (COD) from [PtCl₂(COD)]. The title compound, cis-[PtCl₂{P(4—H₂C=CHC₆H₄) Ph₂}₂], crystallizes in the triclinic spacegroup P1, with the Pt atom on a center of symmetry and each pair of equivalent ligands in a cis orientation. The geometry is a slightly distorted square planar and the Pt atom is slightly elevated out of the coordinating atom plane. The two P atoms are closer to each other but away from the two chloride atoms with angles of P1—Pt—P2 = 96.1 (4)° and Cl1—Pt—Cl2 = 87.7 (4)° whereas the P1—Pt—Cl1 is = 175.1 (4)° and that of P1—Pt—Cl2 being 89.6 (4)°

The title compound compares well with other closely related Pt^II complexes from the literature containing two chloro and two tertiary phosphine ligands in a cis geometry. The title compound, containing Pt—Cl bond lengths of 2.3566 (9) and 2.3336 (9) Å and Pt—P bond distances of 2.2489 (9) and 2.2627 (9) Å, fits well into the typical range for complexes of this kind. Notably the title compound did not crystallise as a solvated complex; these type of Pt^II complexes have a tendency to crystallise as solvates (Meijboom & Omondi, 2011).

Large thermal vibrations on the periphery of the molecule results in a badly defined C═C bond length. Disordered modelling resulted in an unstable refinement.

Experimental top

Diphenylphosphinostyrene (0.05 g, 0.35 mmol) was dissolved in acetone (5 ml). A solution of [Pt(COD)Cl₂] (0.05 g, 0.17 mmol) in acetone (5 ml) was added to the phosphine solution. The mixture was stirred for 5 min, after which the solution was left to crystallise. Yellow crystals of the title compound were obtained.

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.
