The asymmetric unit of the title compound, [Fe(C(3)H(4)N(2))(6)]SO(4)·2C(3)H(4)N(2), contains two complex cations, two sulfate anions and four imidazole mol-ecules. In both cations, the Fe(II) atom is coordinated by six monodentate imidazole ligands and exhibits a slightly distorted octa-hedral coordination geometry. The Fe-N distances [2.184 (4)-2.218 (4) Å] point to a high-spin state of the F...

A series of new conjugated compounds with a -SCH₂- linkage were synthesized by chemical methods from imidazole and coumarin derivatives. The experimental results indicate that of the twenty newly synthesized imidazole-coumarin conjugates, three of them exhibited appealing EC50 values (5.1-8.4 μM) and selective indices >20 against hepatitis C virus. Their potency and selectivity were increased s...

The title compound, C(22)H(16)N(2)O·CH(4)O, is a product of the condensation reaction between phenanthrene-quinone and 4-methoxy-benzadehyde. There are two imidazole mol-ecules and two methanol molecules in the asymmetric unit. The phenanthryl and imidazole rings are almost parallel in both mol-ecules, with inter-planar angles of 6.65 (1) and 5.40 (3)°. The dihedral angles between the imidazole...

In the title salt, C(2)H(8)N(+)·C(10)H(6)N(3)O(5) (-), the imidazole-carboxyl-ate anion is essentially planar [maximum deviation from the least-squares plane = 0.046 (5) Å], with a dihedral angle between the rings of 2.7 (2)°. This conformation is maintained by the presence of both intra-molecular carb-oxy-carboxyl-ate O-H⋯O and imidazole-oxide N-H⋯O hydrogen bonds. Iin the crystal, cation-carb...

Workplace bullying is defined as negative behaviors directed at organizational members or their work context that occur regularly and repeatedly over a period of time. Employees' perceptions of psychosocial safety climate, workplace bullying victimization, and workplace bullying perpetration were assessed within a sample of nearly 5,000 workers. Linear and nonlinear approaches were applied in o...

Photo-oxidation reactions of imidazole derivatives accelerated by quinoid oxidation-state structures, which can be controlled different linking types arylamine groups.

2-Mercapto-1-methyl-imidazoline (N(2)C(4)H(6)S) is converted at room temperature into 2-bromo-1-methyl-imidazole (N(2)C(4)H(5)Br) in presence of copper(I) bromide in acetonitrile-chloroform mixture via extrusion of sulfur as sulfate and oxidation of Cu(I) into Cu(II). 2-Bromo-1-methyl-imidazole was isolated as its self assembled tetranuclear Cu(II) cluster, [Cu(4)(η(1)-N-(N(2)C(4)H(5)Br)(4)(μ(4...

The title compound, [Fe(C(5)H(5))(C(14)H(19)N(2))], is characterized by a ferrocenyl group separated from an imidazole functionality by a straight-chain hexyl unit. The two cyclo-penta-dienyl rings of the ferrocenyl group show a marginal inward tilt of 2.17 (2)°. The imidazole unit, which is essentially planar (with a maximum deviation of 0.007 A for one of the N atoms) and tilted away from the...

The self-assembled (SA) films of imidazole and its derivatives were prepared on the iron surface. The protection abilities of these films against iron corrosion in 0.5 M H2SO4 solution were investigated using electrochemical impedance spectroscopy (EIS) and polarization techniques. The results of EIS and polarization curves demonstrated that films of the imidazole and its derivatives were able ...
