The ligand 1-(1-(pyridin-2-yl)ethylidene)carbonohydrazide (H4L1) and 1-(pyridin-2-ylmethylene)carbonohydrazide (H4L2) were prepared by reaction of carbonohydrazide with 2-acetylpyridine or pyridine carbaldehyde respectively in a reflux methanol solution. complexes are the appropriate metal salt. These well characterized elemental analysis, IR UV spectroscopies their structure determined single X-ray diffraction technic. In crystal dinuclear complex [Mn2(H4L1)2(H2O)4]·Cl4, 1) each Mn(II)...
A new electrosynthesized, fluorescent 4-amino-3-hydroxynaphthalene-1-sulfonic acid-doped polypyrrole (AHNSA-PPy) was used for the detection of Cr(VI), Pb(II) and Cd(II) heavy metallic ions. The optical properties AHNSA-PPy were studied by UV-VIS absorption fluorescence spectrometry in diluted DMSO solutions. spectrum showed a main band at 260 nm, moderate 240 shoulders 285, 295, 320 360 whereas presented an excitation peak 330 nm emission 390 with shoulder 295 nm. effects ions, including...
Dissociation constant, solubility, and thermodynamic data are very important physicochemical parameters for biological substances their knowledge is of fundamental importance the validation drugs. In addition to low cost accessibility, Conductometric pH-metric methods seem be particularly suitable determination these given often weak acidic or basic nature These were determined a new synthesized diisopropylammonium hydrogenmaleate (iPr2NH2-MA) crystalline molecule. used this...
Electrochromic materials are of great interest for their potential in eyewear protection and data storage devices, as they change colors response to electrochemical switching. While many the systems currently used based on inorganic materials, organic such triazenes have emerged viable alternatives due unique properties, including optical properties. Triazenes a class compounds with three consecutive nitrogen atoms an acyclic arrangement, been variety applications medicinal synthetic...
Reactions of the Schiff base N,N-dimethyl-N'-((5-methyl-1H-imidazol-4-yl)methylene) ethane-1,2-diamine (HL), synthesised in situ, with chloride or thiocyanate copper (II) salt; afforded two new mononuclear complexes, [Cu(HL)Cl2]·H2O (1) and [Cu(HL)(SCN)2] (2). These compounds have been studied characterized by elemental analysis, IR UV-Vis spectroscopies, electrochemistry, molar conductivity room temperature magnetic measurements. Single crystal X-ray structure determination complexes...
Complexes of nickel (II) and iron (III) are easily synthetized using the symmetrical ligand 1,5-bis(1-(pyridin-2-yl)ethylidene)carbonohydrazide) (H2L) metal nitrate salts. Square [2x2] grids structure one tetranuclear complex were isolated. X ray diffraction analysis reveals that crystal structures two complexes similar. The asymmetric unit each consists four cationic molecules ions. Each acts in its monodeprotonated form through five coordination sites such as pyridine nitrogen atoms,...
