Bihar, University, Muzzarpur Kendriya Vidyalaya, Muzzarfpur, Bihar (INDIA) <p>Some mixed ligand complexes of the type [M(MQTC)₂X₂] where M = Co(II), Ni(II) and Cu(II), MQTC = 3-methyl (N-O-Toludine)quinazolone thiosemicarbazone, X = Cl^-, Br^-, I^-, NO₃^- and ClO₄^-. The ligand as well as metal complexes were characterized by elemental analysis, IR spectra, electronic spectra, magnetic suceptibility and molar conductance study. The molar conductance measurements of the complexes in DMF corresponds to non electrolytic in nature. On the basis of above observations the ligand MQTC behaves as bidentate manner and coordination proposes through azomethine N and thione sulphur atoms of thiosemicarbazone moiety. The remaining coordination sites are occupied by negative ions such as Cl^-, Br^-, I^-, NO₃^- and ClO₄^-. The complexes were proposed to be octahedral in geometry on the basis of electronic and magnetic susceptibility value.</p> <p>&nbsp;</p> <p>&nbsp;</p> https://journalofchemistry.org/paper/682/ MQTC/ Co Ni Complexs.
