1-(4-Hydroxyphenyl)-2-(2-oxidonaphthalen-1-yl)diazen-1-ium methanol hemisolvate
In the title compound, C16H12N2O2·0.5CH3OH, the H atom of the -OH group has been transfered to the N atom in the azo group, forming a zwitterion. Hence, there is an intra-molecular N-H⋯O, rather than an O-H⋯N, hydrogen bond in the mol-ecule. The mol-ecule is almost planar, the dihedral angle between the benzene ring and the mean plane of the naphthalene ring system being 4.51 (6)°. In the cryst...

In the title zwitterion, C17H12N2O2, the dihedral angle between the benzene ring and naphthalene ring system is 11.76 (7)° and an intra-molecular N-H⋯O hydrogen bond exists. In the crystal, molecules are linked via pairs of C-H⋯O hydrogen bonds, forming inversion dimers.
متن کامل(E)-1-(3-Chlorophenyl)-2-(2-oxidonaphthalen-1-yl)diazen-1-ium
The title zwitterion,, C16H11ClN2O, is approximately planar, the dihedral angle between the benzene ring and naphthalene ring system is 1.55 (13)°; an intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation. In the crystal, π-π stacking between the benzene ring and the naphthalene ring system of adjacent mol-ecules links the mol-ecules into supra-molecular chains running along th...

In the mol-ecule of the zwitterionic title compound, C(17)H(11)N(3)O, the naphthalene ring system is planar [maximum deviation = 0.029 (3) Å] and is oriented at a dihedral angle of 3.55 (3)° with respect to the benzene ring. An intra-molecular N-H⋯O hydrogen bond results in the formation of a planar six-membered ring. In the crystal structure, inter-molecular C-H⋯O inter-actions link the mol-ec...
متن کامل1-{[4-(4-{[(2-Oxidonaphthalen-1-yl)methylidene]azaniumyl}phenoxy)phenyl]iminiumylmethyl}naphthalen-2-olate
The title Schiff base compound, C34H24N2O3, was prepared by a condensation reaction of bifunctional aromatic diamine (4,4'-diamino-diphenyl ether) with hy-droxy-naphtaldehyde. The asymmetric unit contains two independent mol-ecules with similar conformations. The compound contains a central oxygen bridge and two functionalized [(E)-(phenyl-iminio)meth-yl]naphthalen-2-olate units. The dihedral a...
