Two similar asymmetric ONO type tridentate Schiff Base ligand molecules and their spectroscopic, crystallographic thermal properties are comparised. Both of obtained in the study were characterized by 1H-NMR, 13C-NMR, analysis, IR spectroscopy UV-Vis spectroscopy. However able to be as single crystals structures determined crystal X-ray technique. The space group geometric shape 2'-(2-hydroxy-anilidene)-4-hydroxy-pentane (L1) is P212121. There 4 unit cell system L1 ligand. 4'(2-hydroxy-5-chlorine-anilidene)-2-hydroxy-pentane (L2) P21/c. four Although they ligands with structure, has an orthorhombic cells L2 a monoclinic cells. Thermal analysis showed state change point. degraded step. 1H-NMR spectra ligands, which have structures, outline. However, it interesting observe that peaks these carbons observed higher area since chlorine atom attached aromatic ring increases screening effect.. spectroscopic results also show general similarity, but effect stands out.
