TL;DR: Protonation constants of (ATS) ligand and stability constants of its Cu2+, Co2+, Mn2+ and Ni2+ complexes were determined by potentiometric titration method in 50% (v/v) DMSO-water solution at ionic strength of 0.1 M NaNO3.

TL;DR: In this article, the 4-methylphenylamino acetoacetylacetone hydrazone has been synthesized and characterized by elementals analyses, i.r., u.v.t.a and t.r measurements.
Abstract: MnII, FeIII, CoII, NiII, CuII, ZnII, LaIII, RuIII, HfIV, ZrIV and UVI complexes of 4-methylphenylamino acetoacetylacetone hydrazone have been synthesized and characterized by elementals analyses, i.r., u.v.–vis. spectra, magnetic moments, conductances, thermal analyses (d.t.a and t.g.a) and e.s.r measurements. The i.r. data show that, the ligand behaves as a neutral bidentate type (10), (13) and neutral tridentate type (4), (11), (12) and (21) monobasic bidentate type (7) or monobasic tridentate type (2), (3), (5), (6), (8), (14), (15), (16), (18), (19), (20) and (22) or dibasic tridentate type (5), (9) and (17) towards the metal ion. Molar conductances in DMF solution indicate that, the complexes are non-electrolytes. The e.s.r spectra of solid complexes (8) and (10) show axial type spectra with $${\hbox{g}_{\|} > \hbox{g}_{\bot} > 2.0023}$$ , d(x2-y2) ground state with significant covalent bond character. However, complex (12), shows an isotropic type, indicating a octahedral manganese(II) complex. Antibacterial and antifungal tests of the ligand and some of its metal complexes are also carried out and it has been observed that, the complexes are more potent bactericides and fungicides than the ligand.
