| Abstract | ||
| Inthis study we describe the synthesis and characterization of four and six coordinated compounds of Mn(II)with Schiff bases derived from vanillin with amino acids (glycine, L-serine, L-tyrosine, and L-phenylalanine).These complexeswere characterized by many physicochemical methods such as elemental analysis(CHN),magnetic susceptibility, molar conductance as well as spectral studies such as IR and UV-Visible .The analytical data showed that the complexes having the formulas[Mn(VA)(H2O)]2,[Mn2(VA)(CH3COO)(H2O)2],whereA-=serineortyrosine[Mn2(Vg)(CH3COO)(H2O)3],[Mn2(VA*H2)2(H2O)2(NO3)2](NO3)2and Na2[Mn2(VA*)2(H2O)2(NO3)2] , A* = all the amino acids .The ligands behave as Tetradentate coordinating through the atomsNOOO, or tridentate NOO; where V= vanillin, A=amino acids (glycine and phenylalanine) that suggested tetrahedral and octahedral geometry. | ||
