Copper(II) coordination compounds with 8-quinolinaldehyde semicarbazone: Synthesis and structure

Synthesis, Structural and Spectroscopic Characterization of CrIII, FeIII, CoIII, NiII and CuII Complexes with an Asymmetric 1,3,4‐Thiadiazole Ligand

“…These values compare well with those found in compounds 1-3. [52,53] Polynuclear copper complexes linked by alcoholato and chlorido ligands are well known in the literature. Charge neutrality is achieved by additional counterions in the outer sphere of the complexes.…”

Synthesis, antibacterial, and antifungal activities of 8-quinolinealdehyde chalcogensemicarbazones and their copper(II) complexes

“…All HL were synthesized by the literature method [23] in order to prepare 8-quinolinealdehyde semicarbazone starting with 8-quinolinealdehyde and the corresponding chalcogensemicarbazide. The purity of the products was checked by chromatography on Silufol plates, PMR spectra, and elemental analyses for C, H, and N.…”

“…The shift of the equilibrium to the right side was also responsible for the lower solubility of IV as compared with I. When an electron-accepting substituent (C 6 H 5 -or p-FC 6 H 4 -) was added to the terminal N [20,23]. The ligand with a methylated S (HL 6 ) in complex IX was also tridentate but coordinated through 3 N atoms, forming one six-membered and one five-membered metallocycle.…”

“…Regardless of the starting metal-ligand ratio and the order of mixing the solutions, products with a Cu-ligand ratio of 1:1 were always obtained. The effective magnetic moments at room temperature for the previously synthesized [19,20,23,24] and newly synthesized complexes ( -orbital.…”

Indole-7-carbaldehyde thiosemicarbazone as a flexidentate ligand toward ZnII, CdII, PdII and PtII ions: cytotoxic and apoptosis-inducing properties of the PtII complex

“…salicylaldehyde thiosemicarbazone), a D,N,Stricoordination normally takes place (3); [5][6][7][8][9] however examples are found in the literature where the potential O donor atom from a salicylaldehyde thiosemicarbazone does not bind to the metal and the ligand shows an N,S-bidentate mode (4 and 5). [9][10][11] In addition, the S-donor atoms of thiosemicarbazones can bridge metal ions to form dinuclear, 12,13 or multinuclear metal complexes (6). [14][15][16] Other coordination modes observed in thiosemicarbazone metal complexes include S-monodentate (7), [17][18][19] and N(thioamide),S-bidentate (8).…”
