S1. Comment

In the course of our studies upon the reactivity of [(R₃P)₂MCl₂] towards R'₂P–P(SiMe₃)₂ (Domańska-Babul et al., 2007) we have studied the reaction of (ⁱPr₂N)₂P–P(SiMe₃)₂ with [(EtPh₂P)₂PtCl₂]. The title compound was obtained unchanged in the synthesis.

The complex exhibits square-planar coordination that is typical for platinum(II) compounds. The platinum atom is 0.0556 (4) Å above the square plane. The structure is similar to that of [(MePh₂P)₂PtCl₂] (Ho et al., 1982). The square planar geometry is characteristic of complexes having less bulky tertiary phosphines. Significant deviation from planarity is observed with sterically bulky phosphines ligands, as noted in cis-dichlorobis(di-t-butylphenylphosphine)platinum(II) (Krautscheid et al., 1997; Porzio et al., 1980). The bond dimensions involving the platinum atom are typical of [cis-(R₃P)₂PtCl₂] compounds such as for [(MePh₂P)₂PtCl₂]. Weak intermolecular C—H···Cl interactions are also present.

S2. Experimental

The compound was been obtained as yellow powder by the reaction of a solution of ethyl(diphenyl)phosphane in ethanol with a solution of potassium tetrachloroplatinate(II) in water. It was obtained in a crystalline habit from the reaction of (ⁱPr₂N)₂P–P(SiMe₃)₂ with [(EtPh₂P)₂PtCl₂] a 1:1 molar ratio in THF. Crystals were obtained by recrystallization from pentane at 249 K

S3. Refinement

All C–H hydrogen atoms were refined as riding on carbon atoms with methyl C–H = 0.98 Å, methylen C–H = 0.99 Å, aromatic C–H = 0.95 Å and U_iso(H)=1.2 U_eq(C) for aromatic CH, 1.3 for CH₂ groups and 1.5 for methyl groups.

Special details

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 taken

into account individually in the estimation of e.s.d.'s in distances, angles

and torsion angles; correlations between e.s.d.'s in cell parameters are only

used 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.
