چکیده
The title compound, C(12)H(8)ClN(3)O(3), in the crystalline state and in solution, exists in the azo form, as predicted by density functional theory (DFT) calculations. The mol-ecule is approximately planar [the dihedral angle between the rings is 1.83 (8)°], with the nitro group slightly twisted [13.4 (2)°] relative to the benzene ring. Translationally related mol-ecules form stacks along [010] with an inter-planar distance of 3.400 (2) Å. The hydroxy group forms an intramolecular hydrogen bond with the azo N atom.

The title compound, C(15)H(8)Cl(2)N(2)O(2)S, crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the 4-chloro-3-nitro-phenyl ring and the thia-zole ring are 0.5 (1) and 7.1 (1)° and those between the 4-chloro-phenyl ring and the thia-zole ring are 7.1 (1) and 7.4 (1)° in the two mol-ecules. The crystal structure is stabilized by inter-molecular C-H⋯Cl and C-H⋯O ...

Title compound was designed to be a black quencher of pyrene fluorescence. It was made amphiphilic to serve as a membrane-bound probe. The synthesis is a two-step procedure. The first step is a Mitsunobu reaction of [{(phenyldiazenyl)phenyl}diazenyl]phenol with 1,2-O-isopropylideneglycerol. The second step is the cleavage of the isopropylidene protecting group. The title compound has the extinc...

In the cation of the title mol-ecular salt, C(18)H(13)N(4)O(+)·Cl(-)·H(2)O, the dihedral angle between the mean planes of the 1,10-phenanthroline system and the phenol ring is 14.40 (19)°. The crystal packing is stabilized by O-H⋯O hydrogen bonds, weak N-H⋯Cl and O-H⋯Cl inter-molecular inter-actions and π-π stacking inter-actions [centroid-centroid distance = 3.6944 (13) and 3.9702 (12) Å].
