A second polymorph of [1,2-bis­(di-tert-butyl­phosphino)ethane]dichlorido­platinum(II)

Abstract

The title complex, [PtCl₂(C₁₈H₄₀P₂)], contains a Pt^II center in an approximately square-planar geometry [cis angle range = 88.09 (3)–91.39 (3)°; twist angle = 1.19 (5)°]. The Pt—P bond lengths of 2.2536 (8) and 2.2513 (8) Å and the Pt—Cl bond lengths of 2.3750 (8) and 2.3588 (8) Å are normal. This crystal form is a polymorph of a structure reported previously [Harada, Kai, Yasuoka & Kasai (1976 ▶). Bull. Chem. Soc. Jpn, 49, 3472–3477].

Comment

One of the most commonly used Pt(0) precursors, Pt(COD)₂, COD = 1,5-cyclooctadiene, is generally synthesized by the reduction of platinumdichlorides, like Pt(COD)Cl₂, with Li₂(COT), COT = cyclooctatetraene (Green et al., 1977; Crascall & Spencer, 1990), or with SmI₂ (Ogoshi et al., 2004). The latter reduction with 20 equivalents of SmI₂ afforded Pt(COD)₂ in moderate yields (45% average). After addition of chelating ligand 1,2-bis(di-tert-butylphosphino)ethane (dtbpe) to the SmI₂ reduction product, it was observed that some Pt^II remained, based on the formation of the title compound, Pt(dtbpe)Cl₂ (I). An independent synthesis of (I) was performed to support these observations, in which dtbpe was added directly to Pt(COD)Cl₂ (see experimental section). The resulting pure product in 88% yield was characterized by ¹H, ¹³C, ³¹P NMR spectroscopies and by single-crystal X-ray diffraction.

Experimental

Pt(COD)Cl₂, COD = 1,5-cyclooctadiene, was synthesized according to the published procedure (McDermott et al., 1976). Under an atmosphere of dinitrogen, bis(di-tert-butylphosphino)ethane (dtbpe) (212 mg, 0.67 mmol) was added to a light yellow suspension of Pt(COD)Cl₂ (250 mg, 0.67 mmol) in THF (25 ml). The reaction mixture was heated with stirring for 12 h at 373 K. After complete conversion to (I) was verified by ³¹P NMR spectroscopy, the volatiles (THF, COD) were removed in vacuo, leaving the white powdery product (343.4 mg, 0.59 mmol) in 88% yield. Crystals of (I) were grown by vapor diffusion of hexanes into THF.

Refinement

The H-atoms were included in the refinements at geometrically idealized positions with C—H distances 0.98 and 0.99 Å for CH₃ and CH₂ type H-atoms, respectively; U_iso values were 1.5U_eq and 1.2U_eq of the carrier atoms for the methyl and CH₂ groups, respectively. The final difference map showed a residual electron density in the vicinity of H31A atom and was chemically meaningless.

Special details

Experimental. 1H NMR (CDCl3, 20 °C): δ 1.5 (d, 3JHP = 14.1 Hz, 36 H, -(CH3)3), 1.9 (d, 2JHP = 16 Hz, 4 H, -CH2-); 13C NMR (CDCl3, 20 °C): δ 24.5 (d, 1JCP = 33 Hz, -CH2-), 30.4 (s, -(CH3)3), 37.6 (d, 1JCP = 30 Hz, -C-); 31P NMR (CDCl3, 20 °C): δ 75.7 (s, with platinum satellites 1JPPt = 3643.2 Hz).

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 takeninto account individually in the estimation of e.s.d.'s in distances, anglesand torsion angles; correlations between e.s.d.'s in cell parameters are onlyused 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 andgoodness of fit S are based on F2, conventional R-factors R are basedon F, with F set to zero for negative F2. The threshold expression ofF2 > σ(F2) is used only for calculating R-factors(gt) etc. and isnot relevant to the choice of reflections for refinement. R-factors basedon F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger.
