Abstract: In the title compound, [Pt₂(C₆H₆P)₂(C₂₆H₄₈P₂)₂]Cl₂·2CH₂Cl₂·C₆H₁₄, the cation crystallizes as a phosphido-bridged Pt^I dimer [Pt(dcype)(-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)°.
