Metal complexes of 7-hydroxy coumarin hydrazone of s-triazine derivatives derived from 7-hydroxy-8-aceto-N-(4',6'-dichloro-1',3',5'-s-triazine) coumarin hydrazone and transition metals have been synthesized and screened for their antibacterial, antifungal and antiseptic activity. The geometry of the complexes has been proposed. The ligand system co-ordinates with the metal ion in a bidentate manner through the nitrogen atom of hydrazone group.
