Synthesis, spectral and thermal studies of Co(II), Ni(II), Cu(II) and Zn(II) complexes of schiff bases derived from 2-amino-5-aryl-1,3,4-thiadiazole

Article abstract of DOI:10.1080/00945719809351676

Some transition metal complexes of the type ML₂.nH₂O [where M = Co(II), Ni(II) and Cu(II); n = 2 and when M = Zn, n = 0; L = anion of the Schiff bases derived from the condensation of 2-amino-5-phenyl-1,3,4-thiadiazole with 2-hydroxy-1-naphthaldehyde (HL¹) or 2-hydroxyacetophenone (HL²) and derived from 2-amino-5-(2-methoxyphenyl)-1,3,4-thiadiazole and 2-hydroxybenzaldehyde (HL³) or 2-hydroxyacetophenone (HL⁴)] have been synthesized and characterized by elemental analyses, molar conductance, magnetic measurements, infrared and electronic spectral studies. The analytical data show 1:2 metal to ligand stoichiometry of the complexes. Magnetic moments, along with electronic spectral data, suggest a distorted octahedral geometry for the Co, Ni and Cu complexes, whereas, a tetrahedral structure has been proposed for the Zn complexes. The presence of water molecules in the Co(II), Ni(II) and Cu(II) complexes is also indicated by the thermal studies.
