Abstract

Dibenzylideneacetone1a, 2,5-dibenzylidenecyclopentanone 1b, 2,6-dibenzylidenecyclohexanone 1c and 2,5-dibenzylidenecyclopent-3-enone 1d form crystalline stoichiometric complexes with 1,3,5-trinitrobenzene 2a, picryl chloride 2b and picric acid 2c. The structures of these complexes are mediated by multi-point C-HO hydrogen bonds. Some of these patterns of molecular recognition also contain stronger O-HO hydrogen bonds. The C-HO hydrogen bonds within these multi-point supramolecular synthons are generally shorter and more linear than the other C-HO hydrogen bonds found in these complexes.
