1:1 Molecular complex of acridine with 1,2,4,5-benzenetetracarbonitrile: refinement in space group P1[bar]

Abstract

The crystal structure of C_(13)H_9N.C_(10)H_2N_4, which was originally described and refined in space group P1 [triclinic; a = 7.447 (4), b = 7.885 (5), c = 8.072 (9) A, α = 73.93 (9), β = 84.59 (9), γ = 85.85 (6) °, Z = 1; Toupet, Miniewicz & Ecolivet (1989). Acta Cryst. C45, 1044-1047], is better described in P1[bar]. The P1[bar] description entails disorder, with the N and CH groups of the central ring of the acridine molecule being indistinguishable. Revised coordinates are given.
