The crystal structures of (Z)-(ethene-1,2-diyl)bis(diphenylphosphine sulfide), C26H22P2S2 (I), along with its complex with PtII dichloride, dichlorido[(Z)-(ethene-1,2-diyl)bis(diphenylphosphine sulfide)-κ2 S,S′]platinum(II), [PtCl2(C26H22P2S2)] (II), are described here. Compound I features P=S bond lengths of 1.9571 (15) and 1.9529 (15) Å, with a torsion angle of 166.24 (7)° between the two phosphine sulfide groups. The crystal of compound I features both intramolecular C-H⋯S hydrogen bonds and π-π interactions. Molecules of compound I are held together with intermolecular π-π and C-H⋯π interactions to form chains that run parallel to the z-Axis. The intermolecular C-H⋯π interaction has a H⋯Cg distance of 2.63 Å, a D⋯Cg distance of 3.573 (5) Å and a D-H⋯Cg angle of 171° (where Cg refers to the centroid of one of the phenyl rings). These chains are linked by relatively long C-H⋯S hydrogen bonds with D⋯A distances of 3.367 (4) and 3.394 (4) Å with D-H⋯A angles of 113 and 115°. Compound II features Pt-Cl and Pt-S bond lengths of 2.3226 (19) and 2.2712 (19) Å, with a P=S bond length of 2.012 (3) Å. The PtII center adopts a square-planar geometry, with Cl-Pt-Cl and S-Pt-S bond angles of 90.34 (10) and 97.19 (10)°, respectively. Molecules of compound II are linked in the crystal by intermolecular C-H⋯Cl and C-H⋯S hydrogen bonds.
