Abstract Notable differences are observed in reactions of platinum(II) precursor complexes with pyridine-imine ligands of formula 2-C5H4NCH=NCH2-C6H4OR with R = Me or H. The ligand 2-C5H4NCH=N-2-C6H4OMe, L1, gave simple complexes [PtXY(L1)], XY = Me,Me; Me,Cl; Cl,Cl. However, the ligand 2-C5H4NCH=NCH2-2-C6H4OH, L2, gave either [PtCl(κ3-N,N,O-2-C5H4NCH2N=CH-2-C6H4O)], in which the ligand L2 had undergone a proton migration and a deprotonation, or a more complex product arising from reaction with solvent. The ligand 2-C5H4NCH=NCH2-4-C6H4OH, L3, gave a complex [PtCl2(L3)], which formed a polymer in the solid state through intermolecular OH..Cl hydrogen bonding.
