Abstract:

The substituted 1,8-naphthyridines, 2-hydroxy-1,8-naphthyridine-3-carboxylic acid hydrazide (HNch) and 2-hydroxy-1,8-naphthyridine-3-carboxylic acid 0-hydroxybenzylidene hydrazide (HNCHBh) react with acetates of Mn(II), Co(II) metal ions to yield complexes of definite composition. The complexes have been characterized by elemental analysis, thermal, conductance, magnetic studies and IR, electronic, NMR and ESR spectral data. The HNCh and HNCHBh form the complexes of formula [M(HNCh)2] and [M(HNCHBh) (H2O)2] respectively.

Keywords:
