The title compound, C(21)H(18)N(2), was obtained as the product of the reaction between 9-ethyl-9H-carbazole-3-carbaldehyde and aniline in ethanol. The crystal packing is stabilized mainly by C-H⋯π inter-actions between the carbazole benzene rings and the methyl-ene H atoms.

In the title compound, C(8)H(9)N(5), a Schiff base derived from N-methyl-pyrrole-2-carbaldehyde and 3-amino-1,2,4-triazole, the C=N double bond linking the two aromatic rings has a Z conformation. The two rings are twisted by 24.20 (5)°. A chain motif results from N-H⋯N hydrogen bonding.

In the title compound, (C(8)H(20)N)[Re(C(9)H(5)N(2)O(2))Cl(CO)(3)], the Re(I) atom is coordinated facially by three carbonyl groups, the bidentate quinoxaline-2-carbaldehyde ligand and a chloride atom, forming a distorted octahedral geometry.. The crystal packing is controlled by C-H⋯O hydrogen bonding and π-π stacking inter-actions involving the benzene rings, with a centroid-centroid distance...

Isolation and structural elucidation of prune constituents were performed and total 10 compounds were determined by NMR and MS analyses. A novel compound was identified to be 2-(5-hydroxymethyl-2',5'-dioxo-2',3',4',5'-tetrahydro-1'H-1,3'-bipyrrole)carbaldehyde, and 7 phenolic compounds were isolated from prunes for the first time. In addition, antioxidant activity of them was evaluated on the b...

The title compound, [Zn(NCS)(2)(C(12)H(17)N(3)O)], was prepared by the reaction of zinc acetate with pyridine-2-carbaldehyde, 2-morpholinoethyl-amine and ammonium thio-cyanate in an ethanol solution. The Zn(II) atom is five coordinate with a distorted trigonal-bipyramidal geometry, coordinating with three N atoms of the Schiff base (2-morpholinoeth-yl)(2-pyridylmethyl-idene)amine and two N atom...

The title compound (HMF), C(6)H(6)O(3), is one of the products of acid-catalyzed dehydration of high-fructose corn syrup, and has been shown to be toxic to honey bees. The compound was crystallized at 276 K, and it was found that the two independent mol-ecules in the asymmetric unit form an infinite O-H⋯O hydrogen-bonding chain that is linked into a three-dimensional network structure by weak i...

In the approximately planar molecule of the title compound, C(11)H(8)N(4)O(4)S, the dihedral angle between the thio-phene and benzene rings is 5.73 (10)°. In the crystal structure, bifurcated inter/intra-molecular N-H⋯(O,O) hydrogen bonds are present. The intermolecular links lead to inversion dimers containing an R(2) (2)(12) graph-set motif.

The title compound, C(12)H(10)BrN(3), is essentially planar (r.m.s. deviation of all non-H atoms = 0.0174 Å), with a dihedral angle of 0.5 (2)° between the two aromatic rings. In the crystal, mol-ecules are linked by weak N-H⋯N inter-actions, forming a zigzag chain running parallel to [001].
