The reaction of cis-Pt(Ph3P)2Cl2 with 2,4,6-triisopropylbenzenethiol (HTIPT) in benzene at 65 °C yields yellow crystals of cis-[Pt(Ph3P)2(TIPT)Cl] (1), while the reaction of cis-Pt(Ph3P)2Cl2 and HTIPT in benzene at room temperature yields cis-[Pt(Ph3P)2(TIPT)2] (2). In contrast to the tendency of solutions of [Pt(R3P)2(SR′)2] complexes with sterically innocent thiolates to rearrange into a complex mixture of cis and trans complexes and polynuclear materials upon exposure to air, solutions of both 1 and 2 are stable with respect to isomerization and oligomerization. Crystal data: C51H50P2SClPt·2H2O (1·2H2O), monoclinic P21/c, a=16.131(5), b=18.294(3), c=17.803(6) Å, β=110.40(2)°, V=4924(2) Å3, Z=4, Dcalc=1.380 g cm-1; structure solution and refinement based on 2932 reflections converged at 0.074. C66H76P2S2Pt (2), monoclinic P21/n, a=10.854(2), b=20.639(5), c=27.080(6) Å, β=100.43(2)°, V=5966(4) Å3, Z=4, Dcalc=1.325 g cm-3; structure solution and refinement based on 4550 reflections converged at 0.049.
