organic compounds
The title compound, C42H36N6O4, was synthesized via a sequence of reactions in which the product of the reaction between the potassium salt of 1,4-dimethylurazole and 9-bromofluorene was allowed to react with (a) potassium tert-butoxide and (b) o-(ClCH2)2C6H4. The X-ray crystal structure of the title compound features a tilted T-shaped edge-to-face aromatic interaction between the two fluorene moieties and the resultant molecular distortion produces chirality which leads to the formation of a racemic structure. The distortion also causes marked differences in the conformations of the two half-chair triazinedione rings. Intermolecular C—HO interactions produce infinite cross-linked double chains of hydrogen-bonded molecules.
