Caleb AA, Bouhfid R, Essassi el M, El Ammari L. Caleb AA, et al. Acta Crystallogr Sect E Struct Rep Online. 2009 Jul 29;65(Pt 8):o2024-5. doi: 10.1107/S1600536809028736. Acta Crystallogr Sect E Struct Rep Online. 2009. PMID: 21583693 Free PMC article.
Both ring systems are essentially planar [maximum deviation = 0.894 (3) A, r.m.s. deviation = 0.0043 A]. The structure is held together by van der Waals forces [electrostatic interactions between dipoles, OC = 3.002 (2) A] between mol-ecules and by weak pi-pi stacking betw …
