Stable complexes of bivalentmetal ionswith 4–salicyldimino–3,5–dioxo–6– methyl–2,3,4,5–tetrahydro–1,2,4–triazine (Hsalmtz) of composition [M(salmtz)2] (M = CoII, MnII, CuII, NiII, PdII, ZnII, CdII, HgII and PtII), [Cu(salmtz)X] (X = Cl– or Br– ) and [M(salmtz)X] (M= ZnII, CdII or HgIIand X = Cl– , I– or NCS–) have been prepared analyzed and their structure have been suggested from the studies of IR, UV, magnetic susceptibility and electrical conductance measurement. The Hsalmtz and its CuII, ZnII, CdII and HgII complexes were screened for antibacterial viz. E. Coli, B. thuringiensis, S. aureus and antifungal activities on F. oxysproum,A. nigar, A. flavus and R. phaseoli. The complexes were found to be highly effective against antibacterial and antifungal species.
