Preparation, Spectroscopic Studies of (E)-2((2-hydroxybenzylidene) amino)-3-mercaptopropanoic acid Chelates
Journal Title: Asian Journal of Advanced Basic Sciences - Year 2018, Vol 6, Issue 1
Abstract
Three chelates of divalent transition metal ions [Co, Ni and Cu] with (E)-2((2-hydroxybenzylidene)amino)-3-mercaptopropanoic acid (HL1) formed from the condensation reaction of 2-hydroxybenzaldehyde (salicylaldehyde) and L-cysteine have been prepared and studied by using several physiochemical tools, such as; CHNS elemental analyses, molar conductivity, magnetic moment measurements and spectroscopic techniques [IR, 1HNMR, UV-Vis]. The CHNS elemental analysis data show the formation of the chelates in 1:2[M:L] ratio. Whereas, the IR spectral data exhibit the chelation sites of the active groups in the Schiff base towards to the metal ions. The electronic spectral results display the presence of the electronic transitions in the free Schiff bas and its chelates. An octahedral geometrical structure was suggested for all chelates.
