Four transition metal complexes constructed with mixed mercaptotetrazole and 4,4′-bipyridine ligands

Abstract

Based on 5-mercapto-1H-tetrazole-1-methanesulfonic acid disodium salt (Na 2 mtms) and 4,4 0 -bipyridine (bpy) as ligands, four new transition metal complexes, namely {[Cd 2 (mtms)(bpy) 2 (OAc) 2 ]ÁH 2

New palladium (II) complexes with 1‐phenyl‐1H‐tetrazole‐5‐thiol and diphosphine Synthesis, characterization, biological, theoretical calculations and molecular docking studies

“…The biological activity of the complexes was evaluated by the agar disc diffusion method originally designated by Bauer. [ 21 ] And the results are listed in Table 3. The standard error for the experiment was ± 0.03%, and the experiments were repeated three times at the same conditions.…”

“…Recently, many studies were published including complexes of tetrazole‐5‐thiol ligand with metal ions, [ 2–18 ] or with mixed ligand complexes of tetrazole‐5‐thiol with phosphine or amine as co‐ligands. [ 6–11,19–26 ] Transition metal complexes of tetrazole‐5‐thione present a wide range of applications in agriculture, medicine, industry, analytical and organic chemistry, as antibacterial, anti‐fungal, and anti‐inflammatory. [ 1,18,19 ]…”

Synthesis, Solid State, Solution and ESI‐MS Studies of Zinc(II) Cluster Complexes with a Branched Mixed Donor Thiolate Ligand

“…Dinuclear OH‐bridged complexes have been prepared with thiosulfate, tripodal thioimidazolyl ligands, a pentadentate thiosemicarbazone and tridentate mixed NS donor thioether ligands , , . Zinc‐bridging sulfur ligands including thiotetrazole, thioxooxadiazole, a macrocyclic mixed donor thiophenyl ligand, sulfide, and sulfidotetrazole have produced tetranuclear, octanuclear or polymeric complexes through oligomerization. The serendipitously isolated hexanuclear cluster [Zn 6 (SC 6 F 5 ) 10 ( L′′′ ) 2 ] ( L′′′ = (1,2‐bis‐pyridine‐2‐yl[(pyridine‐2‐ylmethylene)‐amino]‐ethenolate) is the only other published complex with a structurally characterized Zn 3 OS 2 metallocycle …”

CuIX (X = Cl−, Br−, I−) inorganic networks separated and stabilized by a mercaptotetrazole ligand

“…Because 5-Mercaptotetrazol and its derivatives are interesting ligands, which can exhibit versatile coordination patterns with metal centers, not only the heterocyclic nitrogen atoms can participate in coordination, but also the sulfhydryl group always adopt [12][13][14][15][16][17][18][19][20]. The sulfhydryl groups, as soft bases, react with metal centers easily [21][22][23][24]. HMTZ ligand has been demonstrated by our previous work to be able to manifest a remarkable coordination versatility in a Cd(II) family with as much as five bridging modes varying from monodentate to tridentate, through the control of inorganic or organic anions [21].…”
