%X The four complexes of zinc (II) and molybdenum (VI) with Schiff base derived from acylhydrazones have been prepared and characterized by elemental analysis, IR, 1H-NMR, thermal analysis and molar conductance studies. Both the two free hydrazones (ligands) that were synthesized acts as a tridentate dianionic ONO donor towards the four complex centers. The conductance measurements in DMF of all the four metal complexes, suggest that they are non-electrolytes. Singlets found in the region 12-14 ppm of the free hydrazones indicates the present of iminol in solution. Also the NMR of zinc complexes was not as a result of its poor solubility. In the FTIR spectra of the free hydrazones, the bands due to carbonyl group were observed in the region 1630-1650cm-1 and these are absent in the spectra of the complexes suggesting enolization and deprotonation of ligands, whereas for the metal complexes, in compounds A and C broad bands observed at 3409 and 3417cm-1 indicates the present of lattice water. In the thermal analysis, there is a weight loss due to lattice in compound A and C
