In benzene-1,2,3-tricarbonitrile, C9H3N3, the packing of the two independent mol-ecules is three-dimensional and complex, involving inter alia bifurcated (C - H)2...N systems from neighbouring CH groups. In [2.2]paracyclo-phane-4,5,12,13-tetra-carbonitrile, C20H12N4, the [2.2]paracyclo-phane systems display the usual distortions, namely lengthened C - C bonds and widened sp 3 angles in the bridges, narrow angles in the six-membered rings at the bridgehead atoms, and flattened boat conformations of the rings. The mol-ecules are linked by a series of C - H...N inter-actions to form layers parallel to the ab plane. International Union of Crystallography 2007.

The design and synthesis of a novel type of bisphthalocyanines, anti-[2.2](1,4)phthalocyaninophanes, were reported. The phthalocyanine dimer exhibited significantly split and red-shifted absorption in the near-IR region and maintained the fluorescence properties of phthalocyanines. The origin of the electronic communication between the two phthalocyanines was rationalized on the basis of the MO model analysis. Copyright
