Synthesis, characterization and antifungal activity of group 12 metal complexes of 2-acetylpyridine-4N-ethylthiosemicarbazone (H4EL) and 2-acetylpyridine-N-oxide-4N-ethylthiosemicarbazone (H4ELO)

Synthesis and Structural Studies of Mn(II), Co(III), and Ni(II) Complexes with Schiff Base Ligands Derived from 2-Acetylpyridine

“…Although many metal-schiff base complexes have been reported, The 1D, 2D, and 3D networks of coordination polymers linked through the bridging of ligands such as dicyanamide, N(CN) 2 − as coligand have been little published. 12,13 In the process of working to extend the dimensionality of the metal-schiff base complexes using benzilic acid (BA) as a bridging ligand, we obtained three different metal -Mn(II), Co(III), and Ni(II) -complexes of acetylpyridine based dithiocarbazate ligand.…”

“…Schiff bases containing N, S donor atoms and their metal complexes have received considerable attention owing to their potent biological activity as anti-fungals, [1][2][3][4] anti-virals, 5 anti-malarials, 6,7 and most notably, as anti-tumor agents.…”

Synthesis, spectroscopic (UV–vis and GIAO NMR), crystallographic and theoretical studies of triazine heterocyclic derivatives

“…However when these ligands are coordinated with a metal atom, they show a remarkable biological activities like anti-microbial, anti-viral and anti-tumor etc. [1][2][3]. 1,2,4-Triazine derivatives of Pd (II) and Pt(II) show monodentate and bidentate behavior [4] due to their tautomeric and ambidentate nature.…”

“…Derivatives of triazines were investigated for their antitumor, fungicidal, herbicidal, insecticidal and activities [5]. Wide use of atrazine as herbicidal compounds 3 resulted in alarming threat for human health as well as environment [6]. Keeping in view the positive and negative aspects of triazine based molecules Larif et al reported a detailed research explaining the biological activities of various derivatives of triazines using DFT and quantitative structure activity relationship (QSAR) studies [7].…”

Synthesis and thermal studies of mixed ligand complexes of Cu(II), Co(II), Ni(II) and Cd(II) with mercaptotriazoles and dehydroacetic acid

“…The importance of similar pyrones as potential fungicides is reinforced by the existence of several natural fungicides possessing structures analogous to 5, 6-dihydro dehydroacetic acid, like alternaric acid, the podoblastins and lachnelluloic acid [3][4][5], studies have shown that such compounds and their complexes have very interesting biological properties [6][7][8][9][10][11][12][13]. Like dehydroacetic acid, mercaptotriazoles and their complexes have been shown to posses enhanced biological activities [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. The work of the present paper is devoted to the synthesis and characterization of some new mixed ligand complexes containing mercaptotriazoles and dehydroacetic acid.…”
