In the title compound, [Pt2(C6H6P)2(C26H48P2)2]Cl2·2CH2Cl2·C6H14, the cation crystallizes as a phosphido-bridged PtI dimer [Pt(dcype)(μ-PPhH)]2Cl2, with crystallographic 2/m symmetry [dcype is 1,2-bis­(di­cyclo­hexyl­phosphino)­ethane]. The Pt2P2 core forms a planar distorted square capped by chelating bis-phosphine ligands, resulting in a distorted square-planar geometry for the Pt atoms. In the Pt2P2 core, the Pt—P bond length is 2.3403 (9) Å, with a narrow P—Pt—P angle of 76.87 (6)° and a wide Pt—P—Pt angle of 103.13 (6)°. The bite angle of the dcype ligand is 85.70 (6)°, with a Pt—P bond length of 2.2993 (11)°.

Special details top

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.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
