Abstract

The crystal structures of (Z)-(ethene-1,2-di­yl)bis­(di­phenyl­phosphine sulfide), C₂₆H₂₂P₂S₂ (I), along with its complex with Pt^II dichloride, di­chlorido[(Z)-(ethene-1,2-di­yl)bis­(di­phenyl­phosphine sulfide)-κ²S,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 Pt^II 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.
