Crystal structure of a bis-4-azatetracyclo[5.3.2.0^2,6.0^8,10]dodec-11-ene-3,5-dione compound

In the molecule of 4-({3-[(3,5-dioxo-4-aza-tetra-cyclo-[5.3.2.0^2,6.0^8,10]dodec-11-en-4-yl)meth-yl]phen-yl}meth-yl)-4-aza-tetra-cyclo-[5.3.2.0^2,6.0^8,10]dodec-11-ene-3,5-dione, C₃₀H₂₈N₂O₄, which contains two substituted [2.2.2]bi-cyclo-octene ring systems linked through a <i>m</i>-xylenedi-amine ring, the six-membered rings of the bi-cyclo-octene ring systems adopt nearly perfect boat conformations as determined from Cremer-Pople analysis. Both ring systems are fused to a five-membered imide ring that is oriented <i>endo</i> to a bridgehead cyclo-propyl ring. The crystal structure features C=O⋯π inter-actions along with C-H⋯O hydrogen bonds.
