Reaction products of α-(1,3-dioxoindane-2-yl)-ethylidine-p-toluidine with Ni2+, Co2+, Mn2+, Zn2+, UO22+ and Th4+ are reported.The ligand, HL, forms complexes of the type ML2.2CH3OH (M=Ni2+, Co2+ and Mn2+), ZnL2 UO2(L)Cl.CH3OH and ThL2.Cl2.These metal chelates were characterized on the basis of elemental analysis, molecular weight, electrical conductivity, IR, far-IR, electronic spectra and magnetic susceptibility measurements.Infrared spectral measurements revealed the monoprotic bidentate nature of the ligand coordinating through the azomethine nitrogen and enolic oxygen.The magnetic susceptibility data of the complexes at 300 K suggested the paramagnetic nature of Ni2+, Co2+ and Mn2+ complexes and the diamagnetic nature of Zn2+, UO22+, and Th4+ complexes.The electronic spectral assignments consistent with the tetrahedral stereochemistry for Zn2+ complexes and the octahedral enviroment for the rest of the metal chelates.These complexes are monomers and nonelectrlytes.
