A comparision of the one-dimensional hydrogen-bonded networks in the crystal structures of hydrogenated phthal­imide derivatives with approximately flat condensed ring systems; (a) (I[link]) [symmetry codes: (i) x − 1, y − 1, z; (ii) y − 1, x, −z], (b) THP [symmetry codes: (i) x, y, 1 + z; (ii) x, −1 − y, [{1 \over 2}] + z], and (c) DTTHP [symmetry codes: (i) x, y, 1 + z; (ii) x, [-{1 \over 2}] − y, [{1 \over 2}] + z].
