Synthesis of heteroleptic Cerium(IV) complexes using a heptadentate (N4O3) tripodale Schiff-base ligand

The Cerium(IV) complexes [{N[CH2CH2N=CH(2-O-3,5-'Bu2C6H2)(3)}CeCl] (1) and [{N[CH2CH2N=CH(2-O-3,5'Bu2C6H2)](3)}Ce(NO3)] (2) were derived from the condensation of tris(2-aminoethyl)amine and 3,5-di-tert-butylsalicylaldehyde and the appropriate Ce starting material CeCl3(H2O)(6) and (NH4)(2)[Ce(NO3)(6)], respectively. Single crystal X-ray diffraction studies reveal monomeric complexes.
