New Dinuclear Schiff Base Complexes of Mn(II) Derived from Amino Acids

Authors
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.
