H-NMR Study of Ternary Platinum(II) Complexes with N-(1- Naphtyl)methyl-1,2-ethanediamine or N-(9-Anthrylmethyl)-1,2- ethanediamine and Bipyridine or Phenanthroline and Restricted Single Bond Rotation Due to Aromatic–Aromatic Ring Interaction
sive study because of its role in (i) the packing of aromatic molecules in the crystalline state, (ii) base-stacking interactions of DNA, (iii) three-dimensional structures of proteins, (iv) molecular recognition of pharmaceuticals by biological receptors or enzymes, and (v) template-directed synthesis. Ternary complexes of platinum(II) or palladium(II) containing 2,2 -bipyridine (bpy) or 1,10-...
متن کاملComplexation equilibrium between iron ( III ) and N , N ’ - bis ( 2 - hydroxyphenylmethyl ) - N , N ’ - bis ( 2 - pyridylmethyl ) - 1 , 2 - ethanediamine
Complexation equilibrium between iron(III) and N,N’-bis(2-hydroxyphenylmethyl)-N,N’-bis(2-pyridylmethyl)-1,2ethanediamine (H2bbpen), a colorless hydrophobic divalent hexadentate ligand, and potential use of the ligand for the spectrophotometric determination of iron(III) in aqueous solution was investigated. In the pH range 2.0 − 3.0, Fe(III) forms stable 1:1 complex with H2bbpen, and Fe(III) c...
متن کاملCrystal Structures and Characterization of Copper(II) Complexes of N,N,N'N'-Tetrakis(2-pyridylmethyl)-1,2-ethanediamine
The structure of [Cu(tpen)](ClO4)2 (tpen = N,N,N',N'-tetrakis(2-pyridylmethyl)-1,2-ethanediamine) has been identified by X-ray crystallography. The copper(II) ion is surrounded by two amine N atoms and three pyridine N atoms of the ligand, making a distorted trigonal-bipyramid. Among the six potential N donor atoms (two amine N and four pyridine N atoms), only one pyridine N atom remains uncoor...

برهمکنش dnaتیموس گاوی طبیعی (ct-dna) با اتیلن دی آمین تترااستات (edta)در بافرtris-hcl با 8/7 ph ( دراین ph،edta به نمک دی سدیم تبدیل می شود) وسسامول در بافر tris-hcl با4/7 ph مورد بررسی قرار گرفته است. edta و سسامول استفاده فراوانی در تکنولوژی غذایی و صنعت شیمیایی دارند. مدل اتصال dna مربوط بهedta بوسیله اسپکتروفتومتری جذب، دورنگ نمایی حلقوی(cd)، ویسکومتری وژل الکتروفورز بررسی شده است. طیفuv ...
15 صفحه اولTernary complexes of copper (II) involving dipeptides and aromatic amines: Effect of n-acidity of aromatic amines on the deprotonation of the peptide group in the ternary complex
Equilibrium constants have been measured potentiometrically for the mixed-ligand complexes, copper (U)-amines (A)-dipeptides (L). The aromatic amines (A) used are 5-nitro-l,lO-phenanthroline (Nphen), 2,2'-pyridyl benzimidazoline (pybz), 1,lO-phenanthroline (phen) and 2,2'-pyridyl imidazoline (pyz). The dipeptides used are glycylglycine (gg), glycyl-l-alanine (ga) and glyeyl-l-Ieucine (gl), The ...
