Reaction of [Pt(κ²-C,N-ppy)(dmso)Cl], 1 (Hppy = 2-phenylpyridine), with Na[H₂B(mb)₂] (Hmb = 2-mercapto-benzimidazole) smoothly afforded the complex {[(κ³-S,B,S-HB(mb)₂]Pt(κ²-C,N-ppy)H}, 2, featuring a strong reverse-dative Pt → B σ interaction in the solid state. When dissolved in thf (or acetone) solution, 2 undergoes a reversible Pt–H bond activation, establishing an equilibrium between the hexacoordinated 2 and the tetracoordinate complex {[(κ²-S,S-H₂B(mb)₂]Pt(κ²-C,N-ppy)}, 3, as ascertained by multinuclear NMR. Hydrolysis of the B–N bond in 2/3 resulted ultimately in the formation of a dimeric half-lantern platinum(II,II) complex [{Pt(κ²-C,N-ppy)(μ₂-κ²-N,S-mb)}₂], 4. The SC-XRD structures of 2 and 4 are reported.
