(a) The π–π stacking and dipole–dipole inter­action modes in (I)[link]. The DICNQ fragment labelled (1) is at the symmetry position (x, y, z), that labelled (2) is at (1 − x, −y, 1 − z) and that labelled (3) is at ([{3\over 2}] − x, [{1\over 2}] − y, 1 − z). The predominantly dipole–dipole inter­actions are indicated by dotted lines, while the π–π stacking is indicated by a double-headed arrow. (b) The inter­molecular hydrogen-bonding scheme (dotted lines) in (I)[link]. The DICNQ fragment labelled (1) is at the symmetry position (x, y, z), that labelled (2) is at (2 − x, −y, 1 − z) and that labelled (3) is at ([{1\over 2}] − x, [{1\over 2}] − y, 1 − z). Zn and Cl atoms are denoted by small spheres. H atoms have been omitted for clarity. Primed atom N23′ is at symmetry position (2) and doubly primed atom N24′′ is at symmetry position (3).
