| Abstract: Condensation of cquimolar quantitics of salicylaldehyde and α-amino aeid(glycinc,alaine, valine, Icucine. phenylalaninc,serine,cystcrin)in absolute methanol-KOH gives the amino-acid schiff bases.Their germanium tetrachloride adducts of the type GeCl4(sal=aa·k)2 have been prepared and characterized by clemental analyses, conductance measurements,IR and 1H-NOR spectra. electronic spectra and thermal analyses, etc. The complexes were either insoluble or only slightly soluble in most organic solvents exeept for DM F,DMSO.Molar conductancc measurements indicate they are ionic compounds. Elemental analysis confirms the 1:2(M:L)stoichiometry of the complexes. The IR spectra and 1H-NMR spcctra of the ligands and the complexes indicate that the schiff bases acted as monodentate ligands coordinating with the metal through their azomcthine nitrigen atom. |
