The College of science organized a seminar about Metal organo-chalcogenide complexes. The Msc. student, Dalal Hameed, has illustrated that In this study, a new series complexes of Cu(II), Ni(II), Zn (II) Co(II) and VO(IV) ions were derived from the novel N,Nʹ-disubstituted thiourea  ligands and the novel thiosemicarbazone ligand, characterization have been by The different techniques and measurements to characterization the free ligand and its complexes like elemental analysis (CHNS), infrared spectra  (FT-IR), 1H-NMR,13C-NMR, mass spectroscopy, UV-visible spectra, magnetic Susceptibility , Molar conductivity  and cyclic voltammetry.  the second study new series adducts formed between (para-substituted phenyl)-1,2,3-selenadiazole compounds  with [[VO(acac)2], ((N,N-Bis(salicylidene)-1,2-Phenylenediamine] . It was also diagnosed with the same previous techniques .
