Key indicators: single-crystal X-ray study; T = 125 K; mean (C-C) = 0.006 Å; R factor = 0.041; wR factor = 0.062; data-to-parameter ratio = 19.5. The title complex (I) can be compared to similar platinum dichloride complexes containing trimethoxy phosphite; [PtCl 2 (P(OMe) 3 ) 2 ] (Bao et al., 1987) and triphenyl phosphine [PtCl 2 (PPh 3 ) 2 ] (Fun et al., 2006) . The geometry at the platinum atom in the title compound (I) bears a closer resemblance to the triphenyl phosphine complex and can be

Experimental 0.8 g (2.14 mmol) of PtCl 2 (COD) was dissolved in the minimum volume of dichloromethane in a round-bottomed flask. To this, 0.921 ml (4.28 mmol) of methyldiphenylphosphinite was added. The solution was then 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, [PtCl 2 (P(OMe)Ph 2 ) 2 ] (1.93 mmol,ca 90%. 31 P-{ 1 H} NMR: δ 85.2 p.p.m. J{Pt-P} 4183 Hz. S3. Refinement All H atoms were included in calculated positions (C-H distances are 0.96 Å for methyl H atoms, 0.97 Å for methylene H atoms and 0.98 Å for methine H atoms) and were refined as riding atoms with U iso (H) = 1.2 U eq (parent atom, methylene and methine H atoms) or U iso (H) = 1.5 U eq (parent atom, methyl H atoms). supporting information sup-2 Acta Cryst.
