The title compound, C17H15N7O4, is a push-pull non-linear optical chromophore containing a di-alkyl-amino donor group and the di-cyano-imidazolyl acceptor separated by a π-conjugated path. The benzene and imidazole rings are not coplanar, making a dihedral angle of 10.0 (2)°. In the crystal, mol-ecules are linked by an extended set of hydrogen bonds and several motifs are recognized. Pairs of m...

      Two series (a and b) of N- substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures...

Racemic and enantiomerically pure �-amino-�-trifluoromethyl alcohols were obtained via sequential nucleophilic trifluoromethylation of selected �-imino ketones, derived from arylglyoxals, and subsequent removal of the MeO or Ph(Me)CH substituent, respectively, located at the N-atom. The obtained products, containing a primary amino group, were used for the synthesis of imidazole N-oxides bearin...

The title compound, C(18)H(16)N(6)·2CH(3)OH, was prepared by the reaction of 5,5'-bis-(bromo-meth-yl)-2,2'-bipyridine with imidazole. The main mol-ecule lies on an inversion center located at the mid-point of the C-C bond joining the two pyridine rings. The asymmetric unit therefore contains one half-mol-ecule and one methanol solvent mol-ecule. The dihedral angle between the pyridine and imida...

The synthesis of 5-substituted 6,6a-dihydroisoindolo[2,1-a]quinolin-11(5H)-ones via [4 + 2] imino-Diels-Alder cyclization from N-aryl-3-hydroxyisoindolinones and N-vinyl lactams under Lewis acid-catalysed anhydrous conditions is reported. Reactions of N-(2-substituted-aryl)-3-hydroxyisoindolinones with N-vinylpyrrolidone under identical conditions resulted in the formation of 2-(2-substitued-ar...

The title compound, [PdBr(C(3)H(5))(C(9)H(8)N(2))], was synthesized by the reaction of the allyl-palladium(II) bromide dimer and 1-phenyl-1H-imidazole. The Pd atom is coordinated by one allyl group [in η(3) mode, the central CH group of the allyl group is disordered over two sets of sites in a 0.668 (5):0.332 (5) ratio], one bromide anion and a 1-phenyl-1H-imidazole ligand. Intra-molecular face...

In the title compound, [Co(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Co(II) ion is located on a twofold rotation axis and shows a distorted octa-hedral coordination configuration, defined by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands in the equatorial plane and two water mol-ecules in the axial positions. In the crystal, O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into a three-dime...

The asymmetric unit of the title mol-ecule, C(9)H(10)N(2)O, contains two mol-ecules. The fused benzene and imidazole rings are nearly coplanar, the largest deviations from the mean plane being 0.025 (3) Å at the non-bridgehead imidazole C atom of one mol-ecule and 0.018 (3) Å at one of the bridgehead C atoms in the other mol-ecule. Intermolecular O-H⋯N and N-H⋯O hydrogen bonds result in the for...

In the title compound, C8H9N4S(+)·Cl(-)·H2O, the cation is approximately planar, with a dihedral angle of 7.71 (8)° between the mean planes of the benzo-imidazole ring system and the thio-urea unit. In the crystal, cations, anions and water molecules of crystallization are linked by O-H⋯Cl, N-H⋯O, N-H⋯Cl and N-H⋯S hydrogen bonds into a three-dimensional network. π-π stacking is observed between...
