2,9-Dichloro-6H,13H-5:12,7:14-di-methano-dibenzo[d,i][1,3,6,8]tetra-azecine
Abstract:
The title compound, C(16)H(14)Cl(2)N(4), is isomorphous with 2,9-dimethyl-6H,13H-5:12,7:14-dimethano-dibenzo[d,i]-[1,3,6,8]tetra-azecine [Rivera et al. (2009 ▶). Acta Cryst. E65, o2553] and has twofold symmetry, with two carbon atoms located on a twofold axis. Only van der Waals forces occur between molecules in the crystal. In the isomorphous compound the crystal structure is stabilized by weak C-H⋯π inter-actions.

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
