Science College, Mansa -382845 (INDIA) <p style="text-align: justify;">Complexes of 2-(8-Quinolinol-5-yl)-amino methyl-3,5-di phenyl-Pyrazoline with Cu(II), Ni(II) and Mn(II) have been synthesized and characterized using elemental analysis, IR spectra, PMR spectra, Reflectance spectra, Conductivity measurements and antimicrobial activity. These studies revealed that they are having octahedral geometry of the type [ML<sub>2</sub> (H<sub>2</sub>O)<sub>2</sub>]. The compounds show net enhancement in activity on coordination of metals with ligand but moderate activity as compared to standard drugs.</p> https://journalofchemistry.org/paper/634/ pyrazoline hydrazinehydrate chalcones Chelates
