Project description:The 12 non-H atoms defining the triple-fused-ring system in the title compound, C(19)H(13)ClN(6), are almost coplanar (r.m.s. deviation = 0.023?Å). The chloro-substituted ring is almost effectively coplanar with the central atoms [dihedral angle = 6.74?(13)°], but the N-bound benzene ring is not [dihedral angle = 54.38?(13)°]. In the crystal, supra-molecular chains along the a axis sustained by C-H?? and ?-? [centroid-centroid distance between N(4)C and C(4)N five-membered rings = 3.484?(2)?Å] stacking occur. A very long C-Cl?? contact is also seen.

Dimethyl 7-meth-oxy-tetra-cyclo-[6.4.0.0(2,4).0(3,7)]dodeca-1(12),5,8,10-tetra-ene-3,4-dicarboxyl-ate.

Project description:The title compound, C(17)H(16)O(5), is a previously unreported substituted semibulvalene cage compound (that is, a tricyclic hydro-carbon formed from one cyclo-propane and two cyclo-pentene rings which also has one double bond fused to a benzene ring). It has one meth-oxy substituent attached to the bridgehead C atom that links only the two cyclo-pentene rings and two methyl carboxyl-ate groups located on the C atom shared by all three non-benzene rings and that shared only between the cyclo-propane and the cyclo-pentene rings. The stereochemistry of the two enanti-omers (racemate) that assemble in each unit cell is RRRS and SSSR. In the crystal, mol-ecules are linked via C-H?O hydrogen bonds and C-H?? inter-actions, forming double-layered sheets lying perpendicular to the a axis.
