A new conglomerate in a series of 2,3:6,7-dibenzobicyclo[3.3.1]nonanes
摘要:
Using enantioselective gas chromatography and X-ray diffraction analysis, we found that compound 2 forms a conglomerate (space group P2(1)2(1)2), whereas, according to X-ray diffraction data, compound 3 crystallises as a racemic compound (space group Pccn).

By way of appending the C2-symmetric carbocyclic cleft diol with thiocarbamates with varying substituents, significant control of the hydrogen bonded network can be achieved. Smaller alkyl substituents lead to the formation of stacked columns of components with the apex of one molecule suitably aligned in the cleft of a second. Aryl substituents, however, lead to the formation of ribbons via an H-bonding
