N’’-[1-(5-chloro-2-hydroxyphenyl)ethylidene]-N'''-[1-(2-hydroxy-5-methylphenyl) ethylidene] carbonohydrazide (H2L1) and N''-[1-(2-hydroxy-5-methyl-3-nitrophenyl) ethylidene]-N'''-[1-(2-hydroxy-5-methyl phenyl) ethylidene] carbonohydrazide (H2L2) with Cu(II), Ni(II),Co(II)and Fe(III) spectrophotometrically investigated it shows 1:1 and 1:2 complex formation between the pH range of 3.0 to 6.0 and also studied by Jobs variation method at 0.1M ionic strength at 300C10C specrtophotometrically. The conditional stability constants are determined for 1:1 complexes. Effect of H2L1 and H2L2 ligand and its complexes on seed germination is also studied.

Unsymmetrical Schiff base, complexes, pH-metry study, spectrophotometric study, seed germination study.
