Crystal structure of a bis-4-aza-tetra-cyclo[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, C(30)H(28)N(2)O(4), which contains two substituted [2.2.2]bi-cyclo-octene ring systems linked through a m-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 endo to a bridgehead cyclo-propyl ring. The crystal structure features C=O⋯π inter-actions along with C-H⋯O hydrogen bonds.
