the copper(ii) complex [cu(pic)2]·2h2o was synthesized with 2-picolinic acid (hpic) and copper acetate as reactants by room temperature solid-solid reaction. the composition and structure of the complex was characterized by elemental analyses, single crystal x-ray diffraction, x-ray powder diffraction, ft-ir spectroscopy and thermogravimetry-differential scanning calorimetry. the crystal struct...

Vinblastine is an important anticancer agent known to diminish microtubule assembly. Ab initio calculations are applied to examine the structural properties and different energies of vinblastine-tubulin complex in different dielectric constants and temperatures. The aims of this work are discovery the best optimized structure and thermodynamic properties of vinblastine-tubulin complex ...

2-Benzylaminopyridine (HBAP) reacts with NaH in THF and generates the sodium salt (NaBAP). Further reaction of [Cu(TMEDA) ] [CuCl ] with one equivalent of this ligand in THF leads to the formation of a dimeric Cu(1) complex, [Cu (BAP)] . H 0. The molecular structure has been determined by using a single-crystal X-ray diffraction method. The yellow compound crystallizes in the monoclinic s...

A symmetric complex [NiL2(H2O)2]Cl2, where L = 2-picolylamine was synthesized and characterized by spectroscopic and structural methods. Single crystal X-ray studies reveal that the Ni(II) center located in a pseudo-octahedral N4O2 environment with bidentate ligands L positioned in basal and two water molecules in the apical position. The complex is solvatochromic, ionochromic and thermochromic...

the internal structure of dna-ctab and dna-ddab is investigated by a small angel x- ray scattering(saxs) instrument. hexagonal packing of dna was observed for dna complex with ctab, and for ddabcomplex is observed lamellar structure. variations in the internal spacing and degree of long-range ordering aredependent on both surfactant type and concentrations of added salt. when we increased the a...

cu2o nanoparticles were synthesized by thermal treatment in liquid paraffin without any inert gas protection using nano structures of schiff base copper (ii) complex (1) as precursor. liquid paraffin was used as solvent and reductant. span 80 was applied to control the morphology of cuprous oxide nanoparticles. the nano structure of the complex was characterized by x-ray diffraction measurement...
