cis-Dichloridobis[tris(4-chlorophenyl)phosphane-[kappa]P]platinum(II) acetonitrile monosolvate

R. Meijboom, L. Kirsten and T. Mbhele

Abstract top

The title compound, [PtCl2(C18H12Cl3P)2]·C2H3N, packs as monomeric units with a square-planar geometry around the PtII atom. The two tris(4-chlorophenyl)phosphane ligands are coordinated in a cis orientation, with P-Pt-P and Cl-Pt-Cl angles of 99.36 (2) and 88.02 (2)°, respectively. In the crystal, C-H...N interactions are observed between the phenyl rings and the acetonitrile solvent molecules.

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 trans/cis-[MX2(L)2] (M = Pt, Pd or Rh; 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(C18H12Cl3P)2] crystallizes in the monoclinic spacegroup P21/c, with the Pt atom on a general position. The cis coordination of the two phosphane ligands results in a distorted square-planar geometry around the Pt atom. This distortion is exemplified by the P1–Pt1–P2 bond angle of 99.36 (2) ° and the Cl1–Pt1–Cl2 bond angle of 88.02 (2) °. The Pt—P bond lengths are 2.2502 (7) and 2.2525 (7) Å, and the Pt—Cl bond lengths are 2.3342 (7) and 2.3454 (7) Å, respectively. The title compound crystallized as a solvated complex with one acetonitrile moiety per molecule.

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 (Davis & Meijboom, 2011; Ogutu & Meijboom, 2011). The Pt–Cl and Pt–P bond lengths compare well with the typical values for complexes of this kind.

In the crystal structure, intermolecular C—H···N interactions are observed between phenyl rings and the acetonitrile solvent molecules.

Experimental top

Tris(4-chlorophenyl)phosphane (0.1235 g, 0.34 mmol) was dissolved in ethanol (25 cm3). Pt(COD)Cl2 (0.05 g, 0.17 mmol) was added to the solution and the mixture was allowed to reflux for 24 h. The solvent was evaporated and a white solid was obtained. Colourless crystals were obtained by recrystallization from acetonitrile, crystals suitable for a single-crystal X-ray diffraction study.

Refinement top

All H positions were calculated after each cycle of refinement using a riding model, with C—H = 0.93 Å and Uiso(H) = 1.2Ueq(C) for aromatic H atoms, and with C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C) for methyl H atoms.

Special details top

Experimental. The intensity data was collected on a Bruker X8 Apex II 4 K Kappa CCD diffractometer using an exposure time of 20 s/frame. A collection frame width of 0.5 ° covering up to θ = 28.4° resulted in 99% completeness accomplished.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
