9-(Trichloroacetylimino)acridine monohydrate.
The title compound, alternatively called N-acridin-9(10H)-ylidene-2,2,2-trichloroacetamide monohydrate, C(15)H(9)Cl(3)N(2)O.H(2)O, crystallizes in space group P2(1)/c with Z = 4. The acridine moieties are arranged in layers, tilted at an angle of 15.20 (4) degrees relative to the ac plane, while adjacent molecules pack in a head-to-tail manner. Acridine and water molecules form columns along the b axis held in place by a network of hydrogen bonds, which is the major factor stabilizing the lattice. The acridine molecule exhibits structural features of both the amino and imino forms, which could be due to the presence of the strong electronegative trichloroacetyl substituent at the exocyclic N atom.
