The comparability of the infrared (IR) spectra of the ligand (1) and its metallic complexes (2)–(11) offers perception into the bonding mechanism between the ligand and the metallic ion. The presence of two sorts of hydrogen bonding, each intra- and intermolecular, is indicated by bands noticed within the 3560–3350 cm⁻¹ and 3340–2980 cm⁻¹ ranges of the ligand²⁰. The upper frequency vary corresponds to a weaker hydrogen bond, whereas the decrease frequency band is related to a stronger hydrogen bond. Moreover, a medium band at 3140 cm⁻¹ is attributed to the v(NH) group^21,22. Curiously, the v(NH) group within the complexes seems on the similar location as within the free ligand, indicating that the NH group doesn’t take part in metallic ion coordination²³. The v(NH) band is found within the metallic complexes inside the 3013–2546 cm⁻¹ vary.

When evaluating the ¹H-NMR of the ligand and the spectra of complicated (5), a major downfield shift of the proton sign in relation to the free ligand is noticed, indicating that the metallic ions are coordinated to the ligand. This shift could possibly be attributed to the formation of a coordination bond (NM)^32,33,34. The proposed formulations of the ligand (1), its Ni(II) complexes (3), and Mn(II) complicated (6) are supported by the mass spectra.
