“…The presence of bands in all complexes in the 430 -450 cm 21 region originate from (M-N) azomethine vibrational modes and identify coordination of azomethine nitrogens [36]. The bands present at 300 -310 cm 21 may be assigned to n(M-Cl) vibrations [33,35]. The bands present at 230 -260 cm 21 in all nitrate complexes are assignable to n(M-O) [33].…”

A novel series of complexes of the type [M(TML)X 2 ]; where TML is Tetradentate Macrocyclic Ligand; M ¼ Co(II), Ni(II), Cu(II), Zn(II)or Cd(II); X ¼ Cl 2 , CH 3 COO 2 or NO 2 3 have been synthesized by template condensation of glyoxal and thiocarbohydrazide in the presence of divalent metal salts in methanolic medium. The complexes have been characterized by elemental analyses, conductance measurements, molecular weight determination, magnetic measurements, electronic, NMR, infrared and far infrared spectral studies. Electronic spectra along with magnetic moments suggest a six coordinate octahedral geometry for these complexes. The low molar conductance values indicates them to be non-electrolytes. The biological activities of the metal complexes have been tested in vitro against a number of pathogenic bacteria to assess their inhibitory potential.

“…The bands present at 300 -310 cm 21 may be assigned to n(M-Cl) vibrations [33,35]. The bands present at 230 -260 cm 21 in all nitrate complexes are assignable to n(M-O) [33]. The characteristic bands due to n(M-S) are not present in the far IR spectra, which again rule out the possibility of coordination through a sulphur atom.…”

A new series of complexes is synthesized by template condensation of glyoxal and oxalyldihydrazide in methanolic medium in the presence of divalent cobalt, nickel, copper, zinc and cadmium salts forming complexes of the type:3 ; OAc À1 . The complexes have been characterized with the help of elemental analyses, conductance measurements, magnetic susceptibility measurements, electronic, n.m.r., infrared and far infrared spectral studies. On the basis of these studies, a six coordinate octahedral geometry for these complexes has been proposed. The biological activities of the metal complexes have been tested in vitro against a number of pathogenic bacteria to assess their inhibiting potential. Most of the compounds have been found to exhibit remarkable antibacterial activities.

Abstract:The bis-1,3,4-oxadiazole-thione and bis-4-amino-1,2,4-triazole-thiol derivatives from L-tartaric acid were synthesized. The synthetic intermediates, ester, hydrazide and oxadiazole derivatives have shown a significant tendency to form complexes with Fe(III), Ni(II) and Cu(II) ions. The formation of complexes with metals was detected by UV-Vis and IR spectroscopy. A novel complex nucleoside from bis-4-amino-1,2,4-triazole-thiol derivative with l-arabinose was also synthesized. The antimicrobial activity for final and synthetic intermediates in vitro against the microorganisms: Escherichia coli, Pseudomonas aeruginosa, Yersinia pseudotuberculosis, Enterococcus faecalis, Staphylococcus aureus and Candida albicans were examined and some products showed noticeable activity against the tested microorganisms.
