The coordination behavior of three ligand precursors 2-[(2- pyridinylmethyl)amino]acetic acid hydrochloride, 4-[(2- pyridinylmethyl)amino]benzoic hydrochloride and 4-{[2-(pyridin-2- ylmethylamino)ethylamino]methyl}benzoic HL1?HCl- HL3?HCl, respectively, in copper(II) complexes is described. were characterized by elemental analysis, ESI mass spectrometry IR spectroscopy, as well X-ray structural...

a series of new heteroleptic chelated copper(ii) complexes that encompass n,n-dibezyl substituted derivative of ethylenediamine (x-diamine) and acetylacetonate (acac) were prepared.  the ir and electronic absorption spectra and the molar conductivity of the complexes are presented and discussed.  the molar conductivity values of the complexes in different solvents reveals a predominance of elec...

A combination of 4-styrylpyridine (spy) and 1-adamantanecarboxylic acid (Hadc) was employed in the assembly reactions with Zn(II) Cu(II) nitrates. The photoreactivity products compared discussed on basis structure–function relationship. Zinc(II) complex 1 is a trinuclear species type [Zn3(spy)2(adc)6] which three zinc(II) atoms are linearly arranged, two adjacent linked by bridging carboxylates...

The corrosion inhibition performance of acetylacetonate complexes of zinc(II), manganese(II), cobalt(II) and copper(II) on the mild steel substrate in 1M H3PO4 was studied using DC polarization. It was seen that the mentioned complexes decreased corrosion rate of mild steel in phosphoric acid media due to the adsorption on metal surface. The potential of mild steel shifted toward more active po...

Nickel (II) and copper (II) complexes of highly unsymmetrical tetradentate Schiff base have been synthesized by the template reaction of half-units N-(1-hydroxy-2-acetonaphtone)-1-amino-2-phenyleneimine (HL) and N-(2-hydroxyacetophenone)-1-amino-2-phenyleneimine (HL1) with the glyoxalphenylhydrazone. The complexes have been characterized by elemental analyses, conductance, IR, 1H NMR and UV spe...

the reaction of copper(ii) chloride and zinc(ii) chloride with n-(2-methylphenyl)-3-(1'-salicylaldehydene-2'-imine-ethane)-butanamide(h2l2a) or (mpsb), n-(2-methylphenyl)-3-(1'-(3'-methoxysalicylaldehydene-2'-imine-ethane)-butanamide (h2l2b) or (mpmsb) and n-(2-methylphenyl)-3-(1'-(2'-hydroxyacetylene-2'-imine-ethane)-butanamide (h2l2c) (mphb) leads to th...

A series of tri- and dimetallic metal complexes of pyridine dicarboxamide cryptates are reported in which changes to the base and metal source result in diverse structure types. Addition of strong bases, such as KH or KN(SiMe3)2, followed by divalent metal halides allows direct access to trinuclear complexes in which each metal center is coordinated by a dianionic N,N,N-chelate of each arm. The...
