The zwitterion of 4-nitro-2-{(E)-[2-(piperidin-1-yl)ethyl]iminomethyl}phenol.
The title Schiff base compound, 4-nitro-1-oxo-2-{(E)-[2-(piperidin-1-yl)ethyl]iminiomethyl}cyclohexadienide, C(14)H(19)N(3)O(3), exists as a zwitterion, with the H atom of the phenol group being transferred to the imine N atom. The C=O, C(Ar)-C(Ar) and C-N bond lengths are in agreement with the oxocyclohexadienide-iminium zwitterionic form. The iminium H atom is engaged in a strong intramolecul...
متن کامل5-Nitro-2-(piperidin-1-yl)benzaldehyde
In the structure of the title compound, C(12)H(14)N(2)O(3), the piperidine ring adopts a chair conformation and the aryl substitutent occupies an equatorial position.
متن کامل(E)-1-Nitro-4-(2-nitroethenyl)benzene
The asymmetric unit of the title compound, C(8)H(6)N(2)O(4), consists of two independent mol-ecules with similar geometries, each adopting a trans configuration about the olefinic double bond. The two mol-ecules are both almost planar (r.m.s. deviations = 0.034 and 0.035 Å) and form a dihedral angle of 83.62 (2)°. Short N⋯O contacts [2.834 (3)-2.861 (3) Å] are observed between the nitro groups ...

The mol-ecule of the title compound, C(13)H(17)N(3)O(4), exists as a zwitterion, with the H atom of the phenol group being transferred to the imine N atom. The C=O, C(Ar)-C(Ar) and C-N bond lengths are in agreement with the oxocyclo-hexa-dienide-iminium zwitterionic form. A strong intra-molecular N(+)-H⋯O hydrogen bond generates an S(6) ring motif. The morpholine ring adopts a chair conformatio...
متن کاملDiiodido{4-nitro-2-[2-(piperidin-1-yl)ethyliminomethyl]phenolato}zinc(II)
In the title complex, [ZnI(2)(C(14)H(19)N(3)O(3))], the Zn(II) atom is four-coordinated by the imine N and phenolate O atoms of the Schiff base ligand, and by two iodide ions in a distorted tetra-hedral coordination. In the crystal structure, mol-ecules are linked through inter-molecular N-H⋯O hydrogen bonds, forming dimers.
