title: Acridine-benzene-1,3,5-tricarb-oxy-lic acid (3/1).
abstract: In the title adduct, 3C(13)H(9)N·C(9)H(6)O(6) or (acr)(3)(btc), associ-ations of one btc and three acr molecules linked by O-H⋯N hydrogen bonds occur. C-H⋯O interactions also occur, resulting in a cyclic hydrogen-bonded synthon R(2) (1)(6). The acr mol-ecules and the btc mol-ecules also form slipped or offset π-π stacking inter-actions [centroid-centroid distances of 3.5212 (17) Å for btc rings and 3.703 (2) and 3.731 (2) Å for acr rings]. Together these inter-actions lead to a three-dimensional network.
