Metal-assisted transformation of N-benzoyldithiocarbazate to 5-phenyl-1,3,4-oxadiazole-2-thiol in the presence of ethylenediamine, and its first row transition metal complexes

Nickel(II) complexes of 5-phenyl and 5-furan-1,3,4-oxadiazole-2-thiones containing ethylenediamine: synthesis, spectral and X-ray characterization

“…(Table 4) is close to the distance reported for other N-HÁÁÁS hydrogen bonds [7]. In addition, the monomeric units of [Ni(pot) 2 (en) 2 ] (1) are held together through N-HÁÁÁS/N intermolecular hydrogen bonding (Table 4), leading to the formation of a wave-like metal-organic framework along the a axis in the supramolecular architecture (Fig.…”

“…As a part of our studies on metal complexes of 1,3, 4-oxadiazole-2-thione [7,14], we report herein the preparation, spectroscopic and X-ray studies of two new Ni(II) complexes based on the heterocyclic ligands Hpot and Hfot. Complexes 1 and 2 were obtained by shaking (Table 1).…”

“…It was reported that 5-phenyl-1,3,4-oxadiazole-2-thiol is antitubercular, and 5-(3-pyridyl)-1,3,4-oxadiazole-2-thiole is both leprostatic and tuberculostatic [5]. Some work has been reported on the metal complexes of 5-phenyl-1,3,4-oxadiazole-2-thione [6,7], 5-(4-pyridyl)-1, 3,4-oxadiazole-2-thione [8][9][10][11][12][13], 5-(3-pyridyl)-1,3,4-oxadiazole-2-thione [14], and 5-(2-pyridyl)-1,3,4-oxadiazole-2-thione [15]. Transition metal complexes of 5-phenyl-1,3, 4-oxadiazole-2-thione (Hpot) have been synthesized, but very little work has been reported on the mixed ligand complexes.…”

Syntheses, structural and thermal studies on Zn(II) complexes of 5-aryl-1,3,4-oxadiazole-2-thione and dithiocarbamates: Antibacterial activity and DFT calculations

“…through either the sulfur or nitrogen atoms, or through both. 1,3,4-Oxadiazole derivatives show diverse biological activities, such as anti-tuberculostatic, anti-inflammatory, anticonvulsant, antibacterial and antifungal activities [16,17]. Potassium salts of N-(aroyl)-hydrazine carbodithioate are important precursors for the syntheses of 1,3,4-oxadiazole and its derivatives [18,19].…”

Manganese(II) complexes of 5-(4-pyridyl), 5-phenyl and 5-(4-methoxy-phenyl)-1,3,4-oxadiazole-2-thione containing 2, 2′-bipyridyl/ethylenediamine: synthesis, spectral, and X-ray characterization

“…The most important natural role of manganese is in the oxidation of water in green plant photosynthesis, where its presence in photosystem II is essential [1,2]. Our current interest in the metal complexes of 1,3,4-oxadiazoles arises from their numerous biological applications such as anti-tuberculostatic, anti-inflamatory, analgesic, antipyretic, and anticonvulsant agents [3,4]. Earlier, we reported on the Cu(II) and Ni(II) mixed ligand complexes of 5-(4-pyridyl)-1,3,4-oxadiazole-2-thione/thiol and 5-(3-pyridyl)-1,3,4-oxadiazole-2-thione/thiol [5,6].…”
