The asymmetric unit of the title compound, {[CoGd(2)(C(5)H(2)N(2)O(4))(2)(SO(4))(2)(H(2)O)(4)]·H(2)O}(n), contains one Co(II) ion, two Gd(III) ions, two imidazole-4,5-dicarboxyl-ate ligands, two SO(4) (2-) anions, four coordinated water mol-ecules and one uncoordinated water mol-ecule. The Co(II) ion is six-coordinated by two O atoms from two coordinated water mol-ecules, as well as two O atoms...

Abstract In this study, the molecular dynamics simulation of imidazole-modified polyacrylamide (VPAM) and (PAM) system showed that VPAM containing had better cohesion-bonding effect than PAM without imidazole. Based on imidazole-containing system, cohesion properties functional monomers mechanism in process were analyzed at high temperature salt, structure-activity relationships between chemica...

In the title compound, [Cd(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)], the Cd(II) atom is coordinated by four carboxyl-ate O atoms from two bidentate chelating 4-methyl-benzoate ligands, two N atoms from two imidazole ligands and one water mol-ecule in a distorted penta-gonal bipyramidal geometry. Inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecule and the carboxyl-ate O...

Boc-protected benzimidazole-pyrrole, benzimidazole-imidazole, and benzimidazole-methoxypyrrole amino acids were synthesized and incorporated into DNA binding polyamides, comprised of N-methyl pyrrole and N-methyl imidazole amino acids, by means of solid-phase synthesis on an oxime resin. These hairpin polyamides were designed to determine the DNA recognition profile of a side-by-side benzimidaz...

In this research, ZnO nanoparticles modified with imidazole in O-xylene solution and characterized with Fourier transform infrared FTIR spectroscopy. Then, polyaniline-ZnO unmodified and imidazole modified nanocomposites were synthesized via in-situ emulsion polymerization method. The synthesized nanocomposites were characterized by FTIR and scanning electron microscopy SEM. The anti-corrosion ...

A novel two-dimensional→three-dimensional Cu(II) coordination polymer, {[Cu2(C10H14N4)5](NO3)4·4H2O} n , based on the 1,1'-(butane-1,4-di-yl)bis-(1H-imidazole) (biim) ligand and containing one crystallographically unique Cu(II) atom, has been synthesized under hydro-thermal conditions. The Cu(II) atom is coordinated by five N atoms from biim ligands, one of which has crystallographically impose...

Two mononuclear copper(II) ibuprofenate adducts with imidazole or 2-methylimidazole and two binuclear copper(II) ibuprofenate adducts with metronidazole or caffeine have been prepared and characterized. Elemental analyses, UV-VIS, IR, EPR, and magnetic moment data for imidazole or 2-methylimidazole adducts are consistent with mononuclear square planar complexes that contain two ibuprofenato lig...

The reaction of equimolar amounts of (n-Bu4N)[ReOCl4] and 2-(1-ethanolthiomethyl)-1methylimidazole (Htmi) in acetonitrile yielded cis-[ReOCl2(tmi)]. An X-ray diffraction study shows that tmi ̄ coordinates as a uninegative N,S,O-tridentate ligand to give distorted octahedral geometry around the rhenium(V) ion. The three donor atoms occupy a triangular face in an octahedron, with the alcoholate ox...

The Cu(II) sites of native, azido- and cyano-derivatives of bovine superoxide dismutase (superoxide:superoxide oxidoreductase, EC 1.15.1.1) have been examined by electron-nuclear double resonance (ENDOR). The ENDOR spectrum of the native protein taken at the g parallel extreme shows resolved structure due to the directly coordinated N-atoms of the histidine ligands. These spectra are too comple...
