2-{(E)-[1-(2-Hydroxyethyl)-3,3-dimethyl-3H-indol-1-ium-2-yl]vinyl}-6-hydroxymethyl-4-nitrophenolate dihydrate
The title merocyanine-type mol-ecule, C(21)H(22)N(2)O(5)·2H(2)O, crystallizes in a zwitterionic form and has an E configuration at the styryl C=C bond. The styryl part of the mol-ecule and the indolium ring are slightly twisted and form a dihedral angle of 13.4 (1)°. The 1.274 (3) Å C-O bond length in the phenolate fragment is the longest among similar mol-ecules. Hydrogen bonds between solvent...

In the title squaraine dye solvate, C26H24N2O2·2CHCl3, the dye mol-ecule is essentially planar, except for the methyl groups, having a maximum deviation over the 26-membered delocalized bond system of 0.060 (2) Å. It possesses crystallographic twofold rotational symmetry with the indole ring systems adopting a syn conformation. The mol-ecular structure features intra-molecular N-H⋯O hydrogen bo...
متن کامل4-[(E)-2-(2-Chlorobenzylidene)hydrazin-1-yl]quinolin-1-ium chloride dihydrate
In the title hydrated salt, C(16)H(13)ClN(3) (+)·Cl(-)·2H(2)O, a small twist is evident in the cation so that the chloro-benzene ring is not coplanar with the central hydrazinyl group [the N-C-C-C torsion angle = -4.8 (12)°]. The conformation about the imine N=C bond [1.284 (10) Å] is E. The components of the structure are connected into a three-dimensional architecture via O-H⋯O, O-H⋯Cl and N-...

In the crystal of the title salt, C(26)H(34)N(2) (2+)·2I(-), the dication lies on a center of inversion that exists along the mid-point of the butyl chain; its five-membered ring is approximately planar (r.m.s. deviation = 0.011 Å). In the crystal, the iodide anion is disordered over two positions in a 1:1 ratio.

In the title compound, C(20)H(20)NO(+)·I(-)·2H(2)O, the cation is almost planar (r.m.s. deviation = 0.038 Å) and exists in an E configuration. The dihedral angle between the quinolinium ring system and the benzene ring is 0.7 (4)°. In the crystal structure, the cations are stacked in an anti-parallel manner along [100] with π-π inter-actions between the pyridinium and ethoxy-benzene rings [cent...
