A series of metal complexes of Zn(II) have been synthesized with newly synthesized biologically active 1,2,4-triazole Schiff bases derived from the condensation of 3-substituted-4-amino-5-mercapto-1,2,4-triazole with 8-formyl-7-hydroxy-4-methylcoumarin. The structure of the complexes has been proposed in the light of elemental analyses, spectroscopic data (IR, UV-Vis, 1 H NMR and FAB-mass), thermal studies. Electrochemical study of the complexes is also reported. All the complexes are soluble to limited extent in common organic solvents but soluble to larger extent in DMF and DMSO and are non-electrolytes in these two solvent. All these Schiff bases and their complexes have also been screened for their antibacterial (Escherichia. coli, S. aureus, S. pyogenes, P. aeruginosa and Salmonella typhi) and antifungal activities (Aspergillus niger, Aspergillus flavus and cladosporium) by MIC method. The brine shrimp bioassay was also carried out to study their in vitro cytotoxic properties.

A simple, rapid and selective method has been developed for the extractive spectrophotometric determination of palladium(II) using 4-(4'-fluorobenzylideneimino)-3-methyl-5-mercapto-1, 2, 4-triazole, (FBIMMT). In hydrochloric acid medium palladium(II) instantly forms stable yellow colored 1:1 complex with FBIMMT at room temperature, which was well extracted in chloroform. The extracted palladium(II)-FBIMMT species showed absorption maximum at 390 nm against reagent blank. The molar absorptivity and Sandell's sensitivity of palladium(II)-FBIMMT in chloroform were found to be 5.404 × 10 3 L mol -1 cm -1 and 0.0196 µg cm -2 respectively. The Beer's law was obeyed up to 17.5 µg mL -1 of palladium(II). The optimal concentration range for maximum precision was evaluated from Ringbom's plot and was found to be 5 to 17.5 µg mL -1 . To establish the optimum extraction conditions; various experimental parameters such as acidity, reagent concentration, solvents, shaking time, interference of cations and anions have been studied. To determine accuracy and precision of proposed method, determinations were carried out at five identical aliquots. The selectivity of the method was enhanced by the use of masking agents. The stoichiometry of the extracted species was assessed by Job's method, mole ratio method and verified by log-log plot. The present method was successfully applied for the separation and determination of palladium(II) from binary mixtures, multi component synthetic mixtures, synthetic mixtures corresponding to alloys and catalyst.

[11][12][13] The pharmaceutical activity of these Schiffbase have been found to get enhanced on complexation with metal ions 14 . The literature reveals that schiff base complexes of 4-(2 / ,4 / -diaminobenzaldimino)-3,5-dimercapto-1,2,4-triazole has not been taken care of .…”

A Schiff base has been prepared by the condensation of 4-amino -3,5-dimercapto, 1,2,4-triazole with 2,4-diaminobenzaldehyde. The ligand has been used for complexation with Mn(II), Cu(II) and Zn(II) metal ions. The complexes have been characterized by their elemental analysis, molar conductivity, magnetic susceptibility, IR spectra and electronic spectra. The very low value of molar conductivity of complexes shows their non-electrolytic nature. The comparison of IR spectra of complexes with that of free ligand reveals that the ligand is coordinated through azomethine nitrogen and deprotonated thiol sulphur forming five membered heterochelates. The magnetic moment values and electronic spectral bands clearly indicate the octahedral geometry around metal ions in complexes
