1-[(1-Benzyl-1H-1,2,3-triazol-4-yl)methyl]-1H-1,3-benzodiazole

The title molecule, C17H15N5, adopts a Z-shaped conformation, with the benzyl and benzodiazole substituents disposed on opposite sides of the plane of the triazole ring. A three-dimensional network is generated in the crystal by a combination of C—H...N hydrogen bonds and C—H...π(ring) interactions.

1-[(1-{[(1S,2R,6R,8R,9S)-4,4,11,11-Tetramethyl-3,5,7,10,12-pentaoxatricyclo[7.3.0.02,6]dodecan-8-yl]methyl}-1H-1,2,3-triazol-4-yl)methyl]-2,3-dihydro-1H-indole-2,3-dione

The title compound,C23H26N4O7, adopts a Z-shaped conformation, with a dihedral angle between the mean planes of the dihydroindole and triazole rings of 70.36 (7)°. In the crystal, C—H...O interactions connect the molecules into zigzag chains running along theb-axis direction.

4-[(1H-Imidazol-1-yl)methyl]-1-(4-nitrobenzyl)-1H-1,2,3-triazole

The title molecule, C13H12N6O2, adopts a slightly twisted zigzag conformation in the crystal, with the dihedral angles between the central triazole ring and the 4-nitrophenyl and imidazole rings being 79.81 (11) and 81.21 (13)°, respectively. The packing features weak C—H...O and C—H...N hydrogen bonds, as well as unusual N=O...π stacking interactions.

4-{[5-Methyl-2-(propan-2-yl)phenoxy]methyl}-1-(4-nitrobenzyl)-1H-1,2,3-triazole

The asymmetric unit of the title compound, C20H22N4O3, comprises two independent molecules (AandB) with markedly different conformations as the C—H bonds of the imidazole rings point in opposite directions. In the crystal, C—H...N hydrogen bonds form chains of molecules extending along theb-axis direction, while C—H...O hydrogen bonds form zigzag chains alonga. Additional intermolecular N...; O...π(ring) contacts form parallel chains of like molecules alonga. The structure was refined as a two-component twin.

Identification of chiral alkenyl- and alkynylcarbinols as pharmacophores for potent cytotoxicity

Illumination by acetylene: Systematic structural variations in a series of archetypal acetylenic lipids derived from the naturally occurring (S,E)-icos-4-en-1-yn-3-ol allowed the discovery of a series of 3R-like 1,4-di-unsaturated carbinol units with a significant and systematic enantiomeric effect on cytotoxicity.
