N-(4-Aminophenyl)-1,8-naphthalimide hemihydrate
The title compound, C(18)H(12)N(2)O(2)·0.5H(2)O, was prepared by the reaction of 1,4-phenyl-enediamine with 1,8-naphthalic anhydride in refluxing dimethyl-formamide. The structure is stabilized by N-H⋯O and O-H⋯O hydrogen bonds. There are π-π stacking inter-actions [centroid-centroid distances of 3.718 (2), 3.510 (2) and 3.546 (2) Å] and C-H⋯π inter-actions between the mol-ecules. The water mol...

In the title compound, C(18)H(10)ClNO(2), the naphthalimide ring system is almost planar, the rings forming dihedral angles of 2.05 (3), 2.26 (3) and 0.80 (3)°. The attached benzene ring of the 4-chloro-phenyl substituent is inclined to the mean plane of the naphthalimide ring system by 75.77 (11)°. In the crystal structure, symmetry-related mol-ecules are linked by C-H⋯O inter-actions. There a...

In the title compound, C(18)H(21)N(3)O(2)S·0.5H(2)O, the benzene ring makes dihedral angles of 88.59 (6) and 40.74 (8)° with the pyridine ring and the amide group, respectively. The water O atom lies on a twofold axis. In the crystal, the organic mol-ecules and the water mol-ecules are linked via O-H⋯O hydrogen bonds, while the organic mol-ecules are connected to each other via N-H⋯O hydrogen b...

The title compound, C14H20N4O4·0.5H2O [systematic name: (2S)-5-{[amino-(iminium-yl)meth-yl]amino}-2-{[(1Z)-4-meth-oxy-2-oxido-benzyl-idene]aza-nium-yl}penta-noate hemihydrate], has been synthesized by the reaction of l-arginine and 4-meth-oxy-salicyl-aldehyde and crystallizes with two independent substituted l-arginine mol-ecules and one water mol-ecule of solvation in the asymmetric unit. Each...
متن کاملN-(3-Chlorophenyl)-4-methylbenzamide hemihydrate
In the title compound, C(14)H(12)ClNO·0.5H(2)O, the water mol-ecule is located on a twofold axis of symmetry. The meta-Cl atom in the aniline ring is positioned anti to the N-H bond. The two benzene rings make a dihedral angle of 40.40 (11)°. The crystal structure is stabilized by inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, which link the mol-ecules into chains along the a axis.
