Hydrogen-bonded dimers in 2-nitrobenzaldehyde hydrazone and a three-dimensional hydrogen-bonded framework in 3-nitrobenzaldehyde hydrazone.
Molecules of 2-nitrobenzaldehyde hydrazone, C7H7N3O2, where Z' = 2, are linked by two N-H...N hydrogen bonds into isolated dimers, whereas in the isomeric 3-nitrobenzaldehyde hydrazone, where Z' = 1, the molecules are linked by one N-H...O hydrogen bond and one N-H...N hydrogen bond into a three-dimensional framework structure.
متن کامل(3-Hydroxy-2-pyridylmethyl)dimethylammonium dihydrogenphosphate.
The title compound, C8H13N2O + H2PO4, is an ionic salt. The organic species is protonated at the N atom of the dimethylaminomethyl group. The dihydrogenphosphate moieties are connected into in®nite chains by way of OÐH O links. The H2PO4 ÿ group also makes an OÐH N hydrogen bond to the pyridine N atom of the organic species. The organic cations crosslink the phosphate chains into a three-dimens...
متن کاملAntimicrobial Study of Newly Synthesized Lanthanide(III) Complexes of 2-[2-hydroxy-3-methoxyphenyl]-3-[2-hydroxy-3-methoxybenzylamino]-1,2-dihydroquinazolin-4(3H)-one
New lanthanide(III) complexes with 2-[2-hydroxy-3-methoxyphenyl]-3-[hydroxyl-3-methoxybenzylamino]-1,2-dihydroquin- azoline-4(3H)-one (Hmpbaq) have been synthesized and characterized by elemental analysis, conductance measurements, magnetic susceptibilities, spectroscopic (IR, NMR, UV, EPR), and thermal studies. Molar conductance studies indicate 1 : 1 electrolytic behavior for these complexes....
متن کاملCrystal structure of 2-hydroxy-N-(2-hydroxyethyl)-N-{2-hydroxy-3-[(E)-N-hydroxyethanimidoyl]-5-methylbenzyl}ethanaminium acetate monohydrate
The structure of the title hydrated mol-ecular salt, C14H23N2O4 (+)·C2H3O2 (-)·H2O, was determined as part of a wider study on the use of the mol-ecule as a polydentate ligand in the synthesis of Mn(III) clusters with magnetic properties. The cation features intra-molecular O-H⋯N and N-H⋯O hydrogen-bond inter-actions. The crystal structure features a range of inter-molecular hydrogen-bonding in...
متن کاملCentral and peripheral antinociceptive activity of 3-(2-oxopropyl)-3-hydroxy-2-oxindoles
Convolutamydine A has been shown to develop a significant antinociceptive effect. Here we demonstrated that new analogues (5-iodo-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Iisa), 5-fluoro-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Fisa), 5-chloro-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Clisa) and 5-methyl-3-(2-oxopropyl)-3-hydroxy-2-oxindole (5-Meisa)), at 0.1-10mg/kg doses, have significant periphe...
