In this study, we have been involved in the synthesis and characterization studies of a new cyclotriorganophosphazenes complex with protected phloroglusine ligand. Firstly,we synthesized hexachlorocyclotirphosphazene from ammonium chloride and phosphorus pentachloride reaction and then two hydroxyl groups of the phloroglusine ligand were protected with methyl iodide and tosyl chloride. Fina...

A new series of transition metal complexes of Co(II), Ni(II), Cu(II) and Zn(II), has beensynthesized from the Knoevenagel condensate Schiff base ligand(L) derived from β-ketoanilideand furfural with o-phenylenediamine and diethylmalonate. Structural features were determinedby spectral and analytical techniques. Square-planar geometry has been adopted by thecomplexes except cobalt complex which ...

New coordination polymer of [HgLCl2]n (1) with HgCl2 and Schiff base bidentate ligand (4-methoxyphenyl) pyridine-2yl methyleneamine (L) was prepared and structurally characterized. In the 1D network structure of 1, the mecury (II) ion adopts an HgN2Cl3 distorted square pyramid geometry. In this complex, one of the chlorine acts as bridging ligand connecting two adjacent mercury(II) ions while, ...

a liquid membrane containing diethylene glycol monobutyl ether (2) shows specificity for k ion in transport while diethylene glycol dibutyl ether (1) was selective for na over k . as an extractant, ligand 2 exhibited pronounced extraction selectivity for k over na in comparison with ligand 1

Here, new N,N′-dipyridoxyl(4,4''-diaminodiphenylether) Schiff-base ligand has been synthesized and characterized by IR, 1H NMR and mass spectrometry. Also, geometry optimization and theoretical assignment of IR spectrum of the ligand have been computed by employing density functional theory (DFT) method. Two pyridine rings and benzene rings in the bridge region are not in the same plane. The ca...

The Cu —O bond lengths in the pseudooctahedral bis(methoxyacetato)diaquo-copper(II) com­ plex are determined by the Jahn-Teller effect on the one hand and by the bonding properties of the three different oxygen ligator atoms (from a carboxylate. water and ether group) on the other. It is derived from EPR single crystal and powder investigations between 4.2 and 350 K, that the system becomes flu...

First, Schiff base iminopyridine ligand has been prepared by the condensation between primary amine, dimethylaniline and active carbonyl group of pyridine carboxaldehyde, then related complexes were synthesized in methanol solution. The ligand and metal complexes have been characterized by elemental analysis, UV, IR, 1 H NMR and 13CNMR spectroscopy. The spectroscopic data of metal complexes ind...
