A 2:1 complex of 1,3‐bis­(9H‐carbazol‐9‐yl)propane and tetra­chloro‐p‐benzoquinone (p‐chloranil)

In the title electron donor–acceptor complex, C27H22N2·0.5C6Cl4O2, the p‐chloranil mol­ecule lies on a crystallographic inversion center, which is located at the center of the benzene ring. In the crystal structure, one p‐chloranil mol­ecule lies above and below the central rings of each donor group of two neighboring 1,3‐bis­(9H‐carbazol‐9‐yl)propane mol­ecules, with a ring‐centroid separation of 3.444 (1) Å. The angle between the planes of the stacking rings of the carbazole and p‐chloranil mol­ecules is 3.4 (2)°.
