- W2777503838 abstract "The present work describes the synthesis, characterization, and spectroscopic studying of cobalt(II), nickel(II), copper(II), and zinc(II) complexes with new bi dentate ligand namely [3-(2-pyridyl)-5-(4-hydroxyphenyl)-2-pyrazoline] which has been prepared by ring closure of(E)-3-(4-hydroxyphenyl)-1-(pyridin-2-yl)prop-2-en-1-one with hydrazine hydrate in (2% w/v) of sodium hydroxide. The new 2-pyrazoline based ligand was identified by melting point, solubility in common organic solvents, mass spectra, NMR and FT-IR spectra. The optimization conditions like acidity, time of reaction, and the molar ratio (M:L) were estimated in order to get the pure colored solid complexes of cobalt, nickel, copper, and zinc(II) by the direct reactions of their metal chlorides in aqueous methanol with the methanolic solution of the ligand. The new metal complexes were characterized by the (C.H.N) elemental analyses, FTIR, UV-Visible spectra, and the molar conductivity in DMSO, and the magnetic susceptibility measurements via Faraday’s method were carried out to reveal the octahedral geometry around the metal ions." @default.
