— Salen type chromium Schiff base complex was synthesized by microwave irradiation. The complex was characterized by UV-visible, FT-IR spectroscopy and EPR spectroscopy. Electrochemical property of chromium complex was tested with the aid of cyclic voltammetry (CV). The synthesized chromium Schiff base complex was electrochemically polymerized and used for the detection of hydroquinone. Chromiu...

Some chromeno[4′,3′-b]pyrano[6,5-b]quinoline derivatives were synthesized by condensation of 2-amino-4-aryl-3-cyano-5-oxo-4H, 5H -pyrano-[3,2-c] chromenes and 1,3-cyclohexanedione in an environmentally benign and efficient method by Cu(II)-Schiff base/SBA-15 as an environmentally friendly heterogeneous and recyclable catalyst under solvent-free conditions in high yields and rates. These kinds o...

New two nano- sized Schiff base complexes [M(L)], where L= 2, 2'-((1E, 1E')-(1, 2 phenylen bis (azanylylidene)) bis (methanylylidene)) bis (4-bromo phenolato) and M=Cu or Zn, (a, b complexes) were synthesized by ultrasonic irradiation. These complexes were characterized by elemental analysis, molar conductivity, FT-IR, fluorescence emission, 1H NMR, field emission scanning electron spectroscopy...

The pyridine-coordinated Cu(II) atom in the title Schiff base complex, [Cu(C(15)H(11)N(3)O(5))(C(5)H(5)N)], is O,N,O'-chelated by the doubly deprotonated Schiff base ligand. The metal centre is in a square-planar coordination geometry.

Schiff bases and their metal complexes in the mixtures of ionic liquid (IL) + organic solvent have shown great potential in attractive oxidation catalytic processes. The efficiency of such a process is strongly dependent on the various molecular interactions occurring between components. Thermodynamic properties of these systems can provide valuable information about structural interactions. Th...

In the title dinuclear complex, [CuGd(C(20)H(22)N(2)O(4))(NO(3))(3)], the Cu(II) ion is located in the inner N(2)O(2) cavity of the Schiff base ligand and adopts a distorted square-planar geometry. The Gd(III) ion is ten-coordinate being bound to ten O atoms, four from the Schiff base ligand and six from three bidentate nitrate anions. The Cu(II) and Gd(III) ions are linked by two phenolate O a...
