The asymmetric unit of the title compound, [Co(C(3)H(4)N(2))(6)][Co(C(3)H(4)N(2))(3)(H(2)O)(3)](C(12)H(6)O(4))(2), contains two halves of crystallographically independent Co(II) complex cations, each assuming a distorted octa-hedral geometry, and one uncoordinated naphthalene-1,4-dicarboxyl-ate dianion. One Co(II) cation is located on an inversion center and is coordinated by six imidazole mol-...

The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely d...

Poly(N-vinylimidazole), PVIm, gels were prepared by gamma-irradiation polymerization of N-vinylimidazole in aqueous solutions as an affinity gel for glucose oxidase (GOx). These affinity gels with a water swelling ratio of 1800% for plain polymeric gel and between 30-80% for Cu(II) and Co(II)-chelated gels at pH 6.0 in phosphate buffer were used in the GOx adsorption studies. Maximum metal ion ...

The asymmetric unit of the title compound, {[Zn(C₁₆H₁₆O₄Si)(C₁₂H₁₀N₄)]·H(2)O}(n), consists of one Zn(II) ion, two half 3,3'-(dimethyl-silanedi-yl)dibenzoate ligands and two half 1,1'-(1,4-phenyl-ene)di-1H-imidazole ligands. The Zn(II) ion is four-coordinated by two O atoms from two carboxlate ligands, two N atoms from two imidazole ligands. Two Zn(II) ions are bridged by two carboxyl-ate groups...

Imidazole compounds are important constituents of atmospheric brown carbon. The imidazole components aqueous secondary organic aerosol (aqSOA) that generated from the evaporation droplets containing pyruvaldehyde and inorganic ammonium on-line characterized by an laser time-of-flight mass spectrometer (ALTOFMS) off-line detected optical spectrometry in this study. results demonstrated desorptio...

UNLABELLED The carcinogenic glutamic acid pyrolysis products 2-amino-6-methyldipyrido [1, 2-a: 3', 2'-d]imidazole (Glu-P-1) and 2-amino-dipyrido [1, 2-a: 3', 2'-d] imidazole (Glu-P-2), and their N-acetyl derivatives were measured in 24-h urine of individual subjects by high-performance liquid chromatography. These compounds were detected in all urine samples analyzed, although the contents vari...

In the title compound, C(10)H(8)N(6), the tetra-zole and benzene rings are close to being coplanar [dihedral angle = 9.90 (16)°], but the imidazole ring is rotated 37.18 (09)° out of the benzene plane. In the crystal, mol-ecules are connected through tetra-zole-imidazole N-H⋯N hydrogen bonds, giving rise to zigzag chains, which extend along [010].

In the crystal structure of the title compound, C(11)H(9)ClN(4)O(3), pairs of N-H⋯N(imidazole) hydrogen bonds connect the mol-ecules into centrosymmetric dimers, which are further connected by N-H⋯O(carbamo-yl) hydrogen bonds into C(4) chains along [010]. Inter-play of these two kinds of hydrogen bonds connect the mol-ecules into layers perpendicular to [101]. The imidazole [maximum deviation 0...

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...

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...
