Coordination isomerism in salicylhydroxamate complexes of platinum(II) and palladium(II). Dalton Transactions (13), 2691-2697.https://hdl.handle.net/10289/194The syntheses of a range of platinum(II) and palladium(II) complexes containing salicylhydroxamate ligands are described. The ancillary ligands, together with the synthetic route, influence the coordination mode of the salicylhydroxamate ligand. Reaction of cis-[PtCl₂(PPh₃)₂] with salicylhydroxamic acid and trimethylamine in hot methanol gave O,O′-bonded [Pt{OC( NO)C₆H₄OH}(PPh₃)₂], but [PtCl₂(cod)](cod = cycloocta-1,5-diene) gave N,O-bonded [Pt{OC₆H₄C(O)NOH}(cod)]. Ligand substitution gives other N,O bonded complexes, including [Pt{OC₆H₄C(O)NOH}(PPh₃)₂]. Reaction of K₂PtCl₄ with 2 equiv. of EPh₃(E = As or Sb), salicylhydroxamic acid and excess trimethylamine gives products whose structures depend on E; AsPh₃ gives [Pt{OC( NO)C₆H₄OH}(AsPh₃)₂], while SbPh₃ gives [Pt{OC₆H₄C(O)NOH}(SbPh₃)₂].enThis article is published in the journal Dalton Transactions, (c) Royal Society of Chemistry 2003Platinum(II) complexes; palladium(II) thiosalicylate complexes; Crystal structuresJournal Article10.1039/b303367h
