Abstract

The thiocarbohydrazone Schiff-base ligand with a nitrogen and sulphur donor was synthesized through condensation of pyridine-2-carbaldehyde and thiocarbohydrazide. Schiff-base ligands have the ability to conjugate with metal salts. A series of metal complexes with a general formula [MCl2 (H2L)]· nH2O (MNi, Co, Cu and Zn) were synthesized by forming complexes of the N1, N5-bis [pyridine-2-methylene]- ...
