Аннотация
Reaction of dinuclear platinum(II) sulfido complex [Pt2(µ-S)2(PPh3)4] with 1,3-propanesultone gives the novel zwitterionic monoalkylated thiolate complex [Pt2(µ-S){µ-S(CH2)3SO3}×(PPh3)4], which was characterized by NMR spectroscopy, electrospray ionisation mass spectrometry, and a single crystal X-ray structure determination. Crystals are monoclinic, space group P2(1)/ c with unit cell dimensions a = 16.8957(3) Å, b = 15.5031(3) Å, c = 28.0121(5) Å, β = 99.780(1)°, for Z = 4.
