(Received 16 February 2010; accepted 19 February 2010; online 24 February 2010)

The title compound, [PdCl2(C8H11O2P)2], has a comparable structure to those of related palladium dichloride complexes containing trimethyl phosphinite and methyl diphenyl phosphinite. The Pd atom is located on a crystallographic twofold rotation axis: thus, there is just one half-mol­ecule in the asymmetric unit. The structure is isomorphous with the platinum analogue cis-[PtCl2{P(OMe)2Ph}2].

Experimental top

Based on the method of Jenkins & Shaw (1966). To (0.3 g (0.93 mmol) of potassium tetrachloropalladate was dissolved in 10 ml e thanol and 0.147 ml (1.86 mmol) of P(OMe)2Ph was added. The solution was stirred at room temperature for 30 min s before being filtered and then precipitated by slow addition of hexane to give a white crystalline solid. Crystals were grown for X-ray crystallography via slow diffusion of hexane into a solution of the product in dichloromethane [cis-PdCl2(P(OMe)2Ph)2] (0.40 mmol, ca. 68 %). 31P-{1H} NMR: δ 125.8 ppm.

Refinement top

All H atoms were included in calculated positions (C—H distances are 0.96 Å for methyl H atoms, 0.93 Å for aromatic H atoms) and were refined as riding atoms with Uiso(H) = 1.2 Ueq(C) or Uiso(H) = 1.5 Ueq(Cmethyl). The highest peak in the difference map is 1.23 Å from atom Pd1.

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).
