Co-operative interactions observed in (I): intermolecular hydrogen-bonded R44(36) hetero-tetramers of AMP and PCT along [111], and association of AMP and PCT into a one-dimensional array along [11], mediated via C—H⋯π and π–π stacking interactions. Cg1 and Cg3 are the centroids of rings C7/C8/C17–C20 and C21–C26, respectively. Only the major fraction of the disorder is shown.
