In the complex (bispyridine -2 and 6-dicarboxylate copper II)) at position H number 26 with modifications of ligands such as vinyl, acetylene and isopropyl, changes in the valance / charge ratio for oxygen and carbon atoms in these complexes have been investigated by methods Initial calculations (ab initio) have been performed at two levels of HF, DFT. Finally, their stability is compared with ...

in this thesis, we exploit a simple and suitable method for immobilization of copper(ii) complex of 4?-phenyl-terpyridine on activated multi-walled carbon nanotubes [amwcnts-o-cu(ii)-phtpy]. this nanostructure was characterized by various physico-chemical techniques. to ensure the efficiency and fidelity of copper species, the implementation of three-component strategies in click-chemistry all...
The self-assembly of copper(II) ions and 5-(2-hydroxyethoxy)benzene-1,3-dicarboxylate (1) leads to Nanoballs in which twelve dinuclear copper(II) paddle-wheel units are interconnected via 24 ligands. The structure of the spherical coordination compound decorated with 24 hydroxy groups has been determined by single crystal X-ray structure analysis. As a model for the integration of Nanoballs int...
Ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. These compounds have been used as ligands for complexation of transition metals, such as copper(II) and nickel(II). According to the spectrosocopic data, copper(II) cation forms (I: 1) and (I:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (I '-isoquinoly1)- 1,1,3,3-tetr...

2,2-dimethylpentanedioic acid (2dmepdaH(2)) and 3,3-dimethylpentanedioic acid (3dmepdaH(2)) reacted with copper(II) acetate to give [Cu(2dmepda)(H(2)O)(3)](2) (1) and [Cu(3dmepda)(H(2)O)(3)](2) (2). Reaction of (1) and (2) with 1,10-phenanthroline and 2,2'-bipyridine yielded [Cu(2dmepda)(phen)(H(2)O)](2)0.5phen (3), [Cu(2dmepda)(bipy)(H(2)O)](2) (4), [Cu(2dmepda)(bipy)(EtOH)](2). 2EtOH (4A), [C...
copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.
Four heteronuclear complexes Mn(CuL)2(SCN)2 (1), {[Mn(CuL)2(mu-dca)2].2H2O}n (2), Zn(CuL)2(SCN)2 (3), and [Fe(CuL)(N3)2]2 (4) incorporating macrocyclic oxamide ligands have been synthesized and structurally characterized. L is the dianion of diethyl 5,6,7,8,15,16-hexahydro-6,7-dioxodibenzo[1,4,8,11]-tetraazacyclotetradecine-13,18-dicarboxylate, and dca is the dicyanamide. The structure of 1 or ...
a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...
