In the title compound, C 18 H 11 Cl 2 NO 2 , the succinimide and cyclobutene rings are individually planar, with a dihedral angle of 66.02 ( 14) between them. The crystal structure is stabilized by CÐHÁ Á Á% interactions involving the phenyl rings.
In the title structure, C~12~H~10~N~4~O^2+^·2ClO~4~ ^−^·H~2~O, the dication is not planar and N—H...O hydrogen bonds link it to perchlorate anions and water molecules. In addition, N—H...O and O—H...O hydrogen bonds link these units into a three-dimensional network.
