Spectral studies and structure of a 2-hydroxyacetophenone 3-hexamethyleneiminyl thiosemicarbazonate(-2) copper(II) complex containing 1,10-phenanthroline

Synthesis, spectroscopic studies and crystal structure of (E)-2-(2,4-dihydroxybenzylidene)thiosemicarbazone and (E)-2-[(1H-indol-3-yl)methylene]thiosemicarbazone

“…Thiosemicarbazones and their metal complexes are a broad class of biologically active compounds [1,2]. Due to this biological activity, there is considerable interest in metal complexes of heterocyclic thiosemicarbazones [3].…”

“…The ligands feature more than two covalent sites, the number of which depends on the aldehyde and on the tautomeric equilibrium of the thiosemicarbazone, although the most common way to coordinate is through the thiolate form [7]. Thiosemicarbazones are an important group of multidentate ligands with potential binding sites available for a wide variety of metal ions [8][9][10]. Tautomerism in Schiff bases with OH group in ortho position to the imino group both in solution and in solid state were investigated using spectroscopy and X-ray crystallography techniques [11][12][13][14][15][16][17][18][19].…”

Synthesis, Spectroscopic Characterization, Computational Exploration of 6-(2-(2, 4-Dinitrophenylhydrazano)-Tetrahydro-2 Thioxopyrimidin-4(1h)-one

“…The occupancy and energies are calculated by NBO analysis. The stabilization energy ÄE i,j associated with delocalization is estimated by the second order perturbative as ... (8) q i -donor orbital occupancy, ei , ejdiagonal elements (Energies of orbital), F (i ,j) -off diagonal NBO Fock or Kohn -Sham matrix element 46 , E (2) -Stabilization Energy.…”

“…Jiang discussed some of the analytical applications like transition metal binders 6 . Some of the important industrial applications were discussed by Sheldrick and John such as plasticizers, stabilizers for polymers as polymerization initiators, catalytic processes, and in waste water treatment [7][8] .…”

Synthesis and Structural Properties of Copper(II), Nickel(II) and Cobalt(II) Complexes with 2,4-Furyliminobenzylacetophenone

“…The chemistry of transition metal complexes with multidentate [1][2][3][4][5][6] ligands have been attracted particular attention because these metal ions can exhibit several oxidation states. The different oxidation states of these complexes showed a strong role in bioinorganic chemistry and redox enzyme system.…”
