Abstract The crystal structure of the title compound (C 24 H 28 N 2 O 4 ) was determined from X‐ray diffraction data using direct methods [CCDC No. 154342]. It crystallized in the non‐ centrosymmetric orthorhombic space group P2 1 2 1 2 1 . The unit cell parameters are : a = 9.351(2), b = 14.191(3), c = 17.051(2)Å, α = β = γ = 90°; Z = 4. The final R factor is 0.054. The central pyridine ring is nearly planar while the outer rings adopt sofa/half chair conformation. Alternate acridine molecules are stacked in an almost parallel manner. The results are compared with those obtained for previously studied two benzoylaminoacridinedione derivatives.
