(E)-1-[(2-Amino-5-nitrophenyl)iminiomethyl]naphthalen-2-olate
The title Schiff base compound, C(17)H(13)N(3)O(3), crystallizes in a zwitterionic form and exists in a trans configuration about the C=N bond. The mol-ecule is slightly twisted, the dihedral angle between the benzene ring and naphthalene ring system being 10.80 (9)°. The nitro group is twisted relative to the plane of the benzene ring [dihedral angle = 8.88 (12)°]. Bifurcated intra-molecular N...

The title zwitterion, C17H14N2O2, crystallizes with two independent mol-ecules in the asymmetric unit, both of which are approximately planar, the dihedral angles between the benzene ring and the naphthalene ring system being 4.39 (12)° in one mol-ecule and 5.83 (12)° in the other, and show an E conformation with respect to the azo double bond. An intra-molecular N-H⋯O hydrogen bond in each mol...

There are two independent zwitterion mol-ecules (A and B) in the asymmetric unit of the title compound, C17H11N3O, which belongs to the family of azo dyes. The dihedral angle between the benzene ring and the naphthalene ring system is 6.99 (6)° in mol-ecule A and 4.38 (6)° in mol-ecule B. The azo group adopts an E conformation with respect to the -N=N- bond and each of the independent mol-ecule...
متن کامل1-[((E)-{2-[(2-Nitrobenzyl)(2-{[(E)-(2-oxidonaphthalen-1-yl)methylidene]azaniumyl}ethyl)amino]ethyl}azaniumylidene)methyl]naphthalen-2-olate monohydrate
The title Schiff base compound, C(33)H(30)N(4)O(4)·H(2)O, adopts an E configuration with respect to each C=N double bond. In the mol-ecule, there are naphthoxide anions and the protonated imino N atoms. Intra-molecular N-H⋯O hydrogen bonds lead to the formation of approximately planar (maximum deviation 0.029 Å for H atom) six-membered rings.. In the crystal, mol-ecules are linked by O-H⋯O and ...
