in this study, bis(salicylaldehyde)-4-methyl-1,2-phenylenediimine (bsmp) as a schiff base ligand of n2o2-type and its mn and fe complex as m-bsmp catalyst were synthesized and characterized by uv-vis, ir spectroscopy and elemental analysis. the efficiency of fe- and mn-bsmp catalysts was evaluated in the oxidative decarboxylation of arylacetic acids with tetra-butylammonium periodate (n-bu4nio4...

Here, we have synthesized the hetero-atoms containing; 3, 4, 6–Triazabicyclo [6, 1] dodeca–1 (12), 2, 6, 8, 10–pentene–5–thione (TBD) macrocyclic Schiff base ligand for application in antituberculosis (anti-TB). This TBD moiety has high donor ability due to presence of three nitrogen atoms, which are also reason interaction between and protein molecule. The is characterized by various spectrosc...

a novel ternary schiff base ligand (hl) of ono type and its copper (ii) complex weresynthesised using 2-aminophenol and o-acetoacetotoluidide. they have been characterised by theusual analytical and spectral methods. the interaction of the complex with calf-thymus (ct)dna has been investigated by uv-vis, viscosity measurement, cyclic voltammetry anddifferential pulse voltammetry studies. the re...

Two distinct coordination geometries are found in the binuclear title complex, [Ni(2)(C(13)H(19)N(2)O(2))(2)(N(3))(2)(CH(3)OH)], as one Schiff base ligand is penta-dentate, coordinating via the anti-cipated oxide O, imine N and amine N atoms (as for the second, tridentate, ligand) but the oxide O is bridging and coordination also occurs through the meth-oxy O atom. The Ni(II) atoms are linked b...

The Sn(IV) atom in the title compound, [Sn(C(6)H(5))(C(14)H(19)N(4)S)Cl(2)], exists within a distorted octa-hedral geometry defined by the N,N',S-tridentate monodeprotonated Schiff base ligand, two mutually trans Cl atoms, and the ipso-C atom of the Sn-bound phenyl group; the latter is trans to the azo-N atom. The greatest distortion from the ideal geometry is found in the nominally trans angle...

A new Schiff base and a new series of Co(II), Ni(II), Cu(II), Cd(II), and Hg(II) complexes were synthesized by the condensation of naphthofuran-2-carbohydrazide and diacetylmonoxime. Metal complexes of the Schiff base were prepared from their chloride salts of Co(II), Ni(II), Cu(II), Cd(II), and Hg(II) in ethanol. The ligand along with its metal complexes have been characterized on the basis of...

New [ML2(H2O)2] complexes, where M = Co(II), Ni(II), Cu(II), and Zn(II) while L corresponds to the Schiff base ligand, were synthesized by condensation of cefotaxime with salicylaldehyde in situ in the presence of divalent metal salts in ethanolic medium. The complexes were characterized by elemental analyses, conductance, and magnetic measurements, as well as by IR and UV-Vis spectroscopy. The...
