Comment

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.

The 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[PPh₂(4–Me₂NC₆H₄)]₂}, crystallizes in the monoclinic space group P2₁/n, with each pair of equivalent ligands in a mutually cis–orientation. The geometry is slightly distorted square planar and the Pt 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 P1—Pt—P2 = 98.43 (7)° and Cl1—Pt—Cl2 = 87.13 (7)°. The Cl1—Pt—P angles are 175.95 (7)° and 84.93 (7)° respectively for P1 and P2. Some weak intermolecular interactions were observed and are reported in Table 1.

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, having Pt—Cl bond lengths of 2.344 (2)Å and 2.3475 (18)Å and Pd—P bond lengths of 2.2490 (19)Å and 2.253 (2)Å, fits well into the typical range for complexes of this kind. It is notable that the title compound crystallized as a solvated complex, as these type of Pt(II) complexes tend to crystallize as solvates.

Experimental

Dichloro(1,5–cyclooctadiene)platinum(II), PtCl₂(COD), was prepared according to the literature procedure of Drew & Doyle (1990). A solution of diphenyl(4–dimethylaminophenyl)phosphine (0.2 mmol) in ethyl acetate (2.0 cm³) was added to a solution of PdCl₂(COD) (0.1 mmol) in dichloromethane (3.0 cm³). Recrystallization from ethyl acetate gave light yellow crystals of the title compound.

Refinement

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

The highest residual electron density peak of 1.53 e×ų is 1.14Å from Pt and the deepest hole of -1.87 e×ų is 0.87Å from Pt representing no physical meaning.

Special details

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 > 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.
