The first structurally characterized three-coordinate bis(phosphine)platinum(0)-sulfur dioxide complex is described, Pt(PCy3)2SO2. The complex crystallized in the monoclinic space group C2/c with a = 23.328 (4) ?, b = 15.181 (3) ?, c = 25.207 (4) ?, and β = 126.17 (1)° with Z = 8 (T = -100°C). The effect of subtle electronic and steric changes on the reactivity of Pt(PCy3)2 and Pt[P(t-Bu)3]2 with the small molecules SO2, CS2, and O2 is demonstrated. Evidence is presented for the first example of a bridged Pt3(μ-CS2)3(PR3)3 moiety.
