0.5 g (1.75 mmol) of PdCl2(COD) was dissolved in dichloromethane (5 mL) in a round-bottomed flask. To this 0.41 mL (3.5 mmol) of trimethylphosphite was added. The solution was stirred for 0.5 h at room temperature. The product was precipitated via slow diffusion of hexane and was then filtered off and dried under vacuum, [PdCl2(P(OMe)3)2] (1.36 mmol, ca 77%). 31P-{1H}NMR: δ 97.9 p.p.m..
All H atoms were included in calculated positions and refined as riding atoms with Uĩso~(H) = 1.5 U~eq~. The highest peak in the difference map is 1.097 Å from atom Pd1.
[PdCl2(P(OMe)3)2] is isomorphous with its platinum analogue [PtCl2(P(OMe)3)2] (2) (Bao et al., 1987) and adopts a cis square planar geometry, Whereas the Pt complex was reported to have quite dissmilar bond lengths for Pt—P1/Pt—P2 and Pt—Cl1/PtCl2 bond lengths these pairs of bonds are equivalent in the title compound.
The Pd—Cl bond bonds in (1) ( Pd(1)—Cl(1) 2.356?(2), Pd(1)—Cl(2) 2.358?(2) Å ) are shorter than the Pt—Cl bonds in (2) whilst the Pd—P bonds ( Pd(1)—P(1) 2.241?(2), Pd(1)—P(2) 2.233?(2) Å ) are longer than the Pt—P bonds in (2). The P—M—P angle ( P(1)—Pd(1)—P(2) 92.38?(8) ° ) is reduced and the Cl—M—Cl angle is enlarged ( Cl(1)—Pd(1)—Cl(2) 89.71?(8) ° ) on going from Pt to Pd with the palladium compound reported here having angles which are closer to ideal square planar .

Refinement. Refinement was performed using all reflections. The weighted R-factor (wR) and goodness of fit (S) are based on F2. R-factor (gt) are based on F. The threshold expression of F2 > 2.0 σ(F2) is used only for calculating R-factor (gt). |

[PdCl2(P(OMe)3)2] is isomorphous with its platinum analogue [PtCl2(P(OMe)3)2] (2) (Bao et al., 1987) and adopts a cis square planar geometry, Whereas the Pt complex was reported to have quite dissmilar bond lengths for Pt—P1/Pt—P2 and Pt—Cl1/PtCl2 bond lengths these pairs of bonds are equivalent in the title compound.
The Pd—Cl bond bonds in (1) ( Pd(1)—Cl(1) 2.356?(2), Pd(1)—Cl(2) 2.358?(2) Å ) are shorter than the Pt—Cl bonds in (2) whilst the Pd—P bonds ( Pd(1)—P(1) 2.241?(2), Pd(1)—P(2) 2.233?(2) Å ) are longer than the Pt—P bonds in (2). The P—M—P angle ( P(1)—Pd(1)—P(2) 92.38?(8) ° ) is reduced and the Cl—M—Cl angle is enlarged ( Cl(1)—Pd(1)—Cl(2) 89.71?(8) ° ) on going from Pt to Pd with the palladium compound reported here having angles which are closer to ideal square planar .
