The oxidative addition of 2,3,4-trithiepin 1-oxide 2 to (Ph₃P)₂Pt(C₂H₄) 5 gives the platinum(II) thiolato thiosulfinato complex cis-{(Ph₃P)₂Pt[S-S(O)-CH₂-C₆H ₄-CH₂-S]} 6. The structure of 2 was established by X-ray structural analysis. 2 crystallizes in the monoclinic space group P2₁/c with a = 878.52(10), b = 1263.4(2), c = 936.95(10) pm, β = 117.818(9)°, Z = 4. The 2,3,4-trithiepin 2-oxide 4 reacts with 5 to form the diplatinum(II) thiolato complex 8. Formally, 1 equiv. SO has been eliminated during this reaction.
