Reaction of Ph 2 SNH ( 1 ) with [PtCl 2 (MeCN) 2 ] (1:1 ratio) in MeCN at 50 °C results in the formation of [PtCl 2 {Ph 2 SNC(Me)NH}] ( 3 ); without heating [Pt(Ph 2 SNH){Ph 2 SNC(Me)NH}Cl]Cl ( 2 ) is the primary product. Attempts to grow X‐ray quality crystals of 3 have not succeeded; it does, however, form a crystalline 2:1 adduct with [PPh 4 ]Cl ( 3a ), the structure of which confirms the presence of the bidentate Ph 2 SNC(Me)NH ligand hydrogen‐bonded to the chloride anion. Reaction of 3 with three equivalents of 1 and two of Tl[PF 6 ] results in the formation of [Pt(Ph 2 SNH) 2 {Ph 2 SNC(Me)NH} 2 ][PF 6 ] 2 ( 4 ), the first example of a complex containing the [Ph 2 SNC(Me)N(H)] unit acting as a monodentate ligand, bound through the nitrogen atom.
