The metal complexes of thiosalicylohydrazide, H2L1 1-R1N2R2R3, R1=R2=R3=H>, and its derivatives H2L2 (R1=H, R2=R3=Me), HL3 (R1=Me, R2=R3=H), H2L4 (R1=R2=H, R3=Ph), and HL5 (R1=Ph, R2=R3=H) have been prepared and characterised.The compounds H2L1, H2L2, and H2L4 act as monobasic bidentate ligands 4)2> where one ligand is bidentate and the other one is tridentate to form a five-co-ordinate neutral chelate> to form neutral chelates.Compounds HL3 and HL5 behave as both bi- and tri-dentate species and form four-co-ordinate cationic aquocobalt(II), aquo- and halogeno-copper(II) Zwitterionic palladium(II) chelates, and five-co-ordinate cationic halogenonickel(II) chelates.The chelating ligands show four types of co-ordination, i.e.N1O, N2S, OS, and N2OS.The structural relationships of the complexes are discussed.
