In the title compound, C14H16N2O4, the ethyl chain of the ethoxycarbonyl group displays rotational disorder. In the crystal structure, the molecules are connected in a three-dimensional network through intermolecular N—HO and O—HO hydrogen-bond interactions.
organic compounds
In the title compound, C9H12N6OS, the pyrazole and triazole rings are nearly coplanar, forming a dihedral angle of 6.50 (9)°. There are N—HN intermolecular hydrogen-bond interactions in the crystal structure, providing stabilization.
metal-organic compounds
In the title compound, {[Mn(C2O4)(H2O)2]·H2O}n, the octahedrally coordinated Mn atom, lying on a twofold rotation axis, is bonded to four carboxyl O atoms from oxalate groups and two O atoms from two water molecules. By means of the bridging oxalate ligand, the title compound exhibits a one-dimensional chain structure. The crystal packing is stabilized by hydrogen bonds of the type O—HO(oxalate).
metal-organic compounds
The tetradentate Schiff base ligand derived from the condensation of 3,5-dibromosalicylaldehyde and 1,2-phenylenediamine, in the presence of pyridine, forms a square-pyramidal five-coordinate Zn complex, [Zn(C20H10Br4N2O2)(C5H5N)]·C3H7N0.
organic compounds
The title compound, C13H13N5S, possesses crystallographically imposed mirror symmetry. In the crystal structure, the molecules interact through strong intermolecular N—HN hydrogen bonds to form ribbons running parallel to the a axis.
organic compounds
In the title molecule, C11H10N4O2, all bond lengths and angles are in normal ranges. In the crystal structure, weak intermolecular C—HN hydrogen bonds link the molecules into centrosymmetric dimers. The crystal packing is further stabilized by van der Waals forces.
organic compounds
The title compound, C10H14O4, is used to cure coughs and clear up phlegm and it is also used as an intermediate in the synthesis of other medicinal products. The entire molecule, except for atoms C10 and O4, is essentially planar (to within 0.001 Å).
organic compounds
In the crystal structure of the title compound, C12H18N4O3, the molecules interact through intermolecular N—HO and C—HO hydrogen bonds to form dimers, providing stabilization.
organic compounds
In the title molecule, C25H20FN3O2S, the central tricyclic system is essentially planar. All bond lengths and angles are within normal ranges. The crystal packing is stabilized by π–π stacking interactions and van der Waals forces.
organic compounds
The title compound, C14H12BrNO2, was prepared from 2-hydroxy-3-methoxybenzaldehyde and 4-bromophenylamine. The 4-hydroxy-3-methoxyphenyl and bromobenzene groups are trans with respect to the imino bond. The planarity of the molecule is supported by the conjugation of the imino group and the aromatic system, together with a resonance-assisted intramolecular hydrogen bond [O—HN = 2.610 (3) Å].
organic compounds
In the title compound, C17H16O6, the asymmetric unit contains one half-molecule. A twofold rotation axis passes through the C atom linking the two rings. Intramolecular O—HO hydrogen bonds seem to be effective in stabilizing the molecular structure.
