      Abstract
      One-pot reactions of [MCl₂(cod)] (cod=cyclo-octa-1,5-diene; M=Pt, Pd) with two equiv of PPh₃ or AsPh₃, one equiv of thiosalicylic acid, and an excess of triethylamine base, followed by the addition of excess Na[BPh₄] to the hot reaction mixture gives complexes [(Ph₃E)₂M(SC₆H₄CO₂) HNEt₃]⁺[BPh4]⁻ (E=P, As). Analogous pyridinium and platinum–thioglycolate [(Ph₃P)₂Pt(SCH₂CO₂)] derivatives were also prepared. An X-ray crystal structure determination on [(Ph₃P)₂Pt(SC₆H₄CO₂) HNEt₃]⁺[BPh₄]⁻ reveals hydrogen-bonding between the NH proton and the carbonyl group of the thiosalicylate ligand, the major effect of which is to flatten the platinum–thiosalicylate moiety. NMR spectroscopic data indicate that the hydrogen-bonding interaction persists in solution.
