Complexes of the type M2[Me(IDA)2] and MeIDA.n H2O, where M = H+, Li+, Na+, K+, 1/2 Ba2+, Me = Mn2+, Fe2+ and IDA = [NH(CH2COO)2]2- were prepared in the solid state. The magnetic properties, thermal stability and electron and infrared spectra of these substances were studied. It followed from the results that both prepared types of complex have a high spin octahedral configuration. In contrast to M2[Me(IDA)2] type complexes, complexes of the Me IDA . nH2O type have polymeric character.
