Abstract: The complexes [(UO2)2(CH2L)(H2O)4] (1), [M4(CH2L)2(H2O)4].4H2O [M= Zn (2) and Cu (3)], (M1)2[(UO2F)2(CH2L)(H2O)2] [M = K (4), Na (6)], M1[(UO2)2(CH2L) (OAc)(H2O)2 ] [M = K (5), Na (7)], K 4[(MF)2(CH2L)2].4H2 [M = Zn (8) and Cu (9)] have been synthesized from reaction of appropriate metal salts with bis(2-hydroxy-1-naphthaldehyde)malonoyl-dihydrazone (CH2LH4) in different experimental conditions in ethanol/methanol media. The complexes have been characterized by elemental analyses, molecular weight, molar conductance, magnetic moment and ESR data. The structural assessment of the complexes has been carried out on the basis of electronic, infrared, 1H NMR and 13C NMR spectral studies.
