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

Abstract

In the title electron donor-acceptor complex, C27H22N2 center dot-0.5C(6)Cl(4)O(2), 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) angstrom. The angle between the planes of the stacking rings of the carbazole and p-chloranil molecules is 3.4 (2)degrees.
