چکیده
In the title compound, C(15)H(15)N(5)O(2), the nitro O atoms are disordered over two sets of sites with an occupancy ratio of 0.75 (4):0.25 (4). Amine-imine tautomerism is observed in the formazan group. This was evident from the similar C-N bond distances in the formazan [1.319 (2) and 1.332 (3) Å], as well as the distribution of the imine proton in the Fourier difference map which refined to a 0.53 (3):0.47 (3) ratio. C-H⋯O and π-π inter-actions [centroid-centroid distances = 3.4813 (1) and 3.3976 (1) Å] are observed in the crystal packing.

In the title mol-ecule, C24H20Cl2O2, the central methyl-benzene ring forms dihedral angles of 42.47 (10) and 34.34 (10)° with the terminal 4-chloro-phenyl fragments. The dihedral angle between the chloro-benzene rings is 34.45 (11)°. A weak intra-molecular C-H⋯O inter-action generates an S(6) ring motif. The crystal packing exhibits weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions.

The title compound, C(19)H(18)O, crystallizes in a non-centrosymmetric space group although the mol-ecule has no chiral centre. The dihedral angle between the aromatic rings is 20.43 (13)°. The structure is stabilized by two intra-molecular hydrogen bonds, and by four π-π and three C-H⋯π inter-actions between the aromatic rings. The perpendicular distances between the centroids of the rings inv...

The asymmetric unit of the organic-inorganic hybrid salt, 2C(9)H(14)N(+)·C(10)H(6)O(6)S(2) (2-)·2H(2)O, consists of one dimeth-yl(4-methyl-phen-yl)ammonium cation, one half of a naphthalene-1,5-disulfonate anion lying on a crystallographic centre of inversion, and one water mol-ecule. In the crystal, O-H⋯O(S) and N-H⋯OH(2) hydrogen bonds link the cations and anions forming ring motifs.

1,5-Bis(4-hydroxy-3-methoxyphenyl)-1,4-pentadiene-3-one (2) was isolated from Curcuma domestica as a curcumin (1)-related compound, which we named C5-curcumin. Intrigued by the potent antitumor activity of C5-curcumin (2)-related 1,5-bisaryl-1,4-pentadiene-3-ones [bis(arylmethylidene)acetones, termed C5-curcuminoids], we previously conducted a structure-activity relationship study of C5-curcumi...
