چکیده
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 molecule lies on a twofold rotation axis. Its two H atoms are disordered equally over two positions.

A series of novel N-n-butyl-1,8-naphthalimide derivatives were synthesized via a three-step reaction involving nucleophilic substitution and acylation. All of the compounds were characterized by IR, 1H NMR, 13C NMR, MS, and elemental analysis, and the crystal structure of N-n-butyl-4-[N’,N’-bis(2`,4`-dichlorobenzoyl)ethylamino]-1,8-naphthalimide was determined. The π-π stacking interactions and...
