Co(II), Ni(II), Cu(II), Th(IV) and UO2(II) complexes with Schiffbases derived from 2-aminopyridine with salicylaldehyde L1, p-hydroxybenzaldehyde L2 and vanillin L3 have been prepared. The complexes have been characterized by elemental analysis, UV, visible and IR-spectra as well as conductance measurements. It is concluded that the molecules and not anions of L1 are coordinated to the metal ion as
