Schiff base ligand (E)-4-[(hydroxyl phenylimino)methyl]benzene-1, 2-diol (H3L) was prepared from the condensation reaction of Protochatechu aldehyde (3, 4-dihydroxybenzaldhyde) with 2-amino phenol. From the direct reaction of the ligand (H3L) with Co(II), Ni(II) and Cu(II) chlorides and Fe(III) and Zn(II) nitrates in 2M:1L molar ratio, the five new neutral complexes were prepared. The character...

A new series of photo-luminescent Zn(II) and Mg(II) Schiff base complexes were prepared by treatment of the arylethynyl-substituted salicylaldehydes obtained from the Sonogashira reaction with the metal salt followed by addition of the different diamines. Most square-planar Zn(II) complexes exhibited good quantum efficiencies. The Mg(II) complexes displayed even higher quantum yields than the c...

A series of coordination compounds have been prepared with tridentate Schiff base ligands, 2 ethyl-[(hydroxy propyl)]3, 1 (4H) quinazoline4-semicarbazone [EHPQS) and 2-ethyl-[(hydroxy propyl)]3, 1 (4H) quinazoline4-thiosemicarbozone [EHPQT]. The obtained complexes were characterized by molar mass, elemental analysis, infrared spectra, electronic spectra, magnetic susceptibility molar conductanc...

The title compound, [Cd(H(2)O)(6)][Cu(C(15)H(17)N(2)O(4))](2)·2H(2)O, has a chiral structure. Copper has a square-planar coordination with two N and two O atoms of the quadridentate chiral Schiff base ligand. The Cd(2+) ion is coordinated by six aqua ligands with a slightly distorted octa-hedral configuration. Ions are linked by O-H⋯O hydrogen bonds, and the [Cd(H(2)O)(6)](2+) cations and [CuL]...

A condensation reaction of 2-amino-1,3,4-thiadiazole with 2-pyrrolecarboxaldehyde to form tridentate NNN donor Schiff base has been performed. The prepared Schiff base was further used for the formation of metal complexes having stoichiometry [M(L)(2)]X(n), where M=Cu(II) or Zn(II), L=N-(2-pyrrolylmethylene)-2-amino-1,3,4-thiadiazole, X=SO(4) (2-), NO(3) (-), C(2)O(4) (2-) or CH(3)CO(2-) and n=...

A new Schiff base has been synthesized from 3-(3-nitrophenyl)-1-phenyl-1H-pyrazole-4carbaldehyde and O-amino phenol. Metal complexes of the Schiff base have been synthesized from acetate salt of Cu (II), Co (II) and Ni (II) metal in the alcoholic medium. The newly prepared Schiff base ligand and metal complexes have been characterized by various physicochemical techniques such as Elemental anal...

In this paper, plate-like NiO nanoparticles were prepared by one-pot solid-state thermal decomposition of nickel (II) Schiff base complex as new precursor. First, the nickel (II) Schiff base precursor was prepared by solid-state grinding using nickel (II) nitrate hexahydrate, Ni(NO3)2∙6H2O, and the Schiff base ligand N,N′-bis-(salicylidene) benzene-1,4-diamine) for 30 min without using any solv...

Schiff bases are versatile ligands and known to be synthesized from the condensation of an amino compound with carbonyl compounds. These compounds along with their metal complexes are considered to be an important as catalysts in various biological processes. Also Schiff base complexes are gaining popularity among the various industries including polymers, dyes and pharmaceutical. This review s...

in this paper, the structure of a new 16-membered macrocyclic schiff base compound n,n′-(3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzylidene)propane-1,3-diamine, c22h26n2o4 (1), derived from 1,3-propanediamine and 3,3′-dimethoxy-2,2′-(propane-1,3-diyldioxy)dibenzaldehyde has been studied by single crystal x-ray diffraction, dft calculations at b3lyp/6-31g** and ft-ir spectroscopy. the titl...

one of the best and the most active ways for surveying thermal behaviour of materials is using differential scanning calorimetry. in this paper, the authors have studied thermal behaviour for schiff base ligand and their synthesized cobalt, nickel complexes. in this method, the sample is opposed to a controlled temperature change and its physical properties. here we studied melting point and tg...
