Abstract

Crystallization of 2,4,5,7-tetranitro-9- (dicyanomethylene)fluorene [DTeF; systematic name: 2-(2,4,5,7- tetranitro-fluorene-9-ylidene)propanedinitrile] and 2,4,5,7- tetranitrofluoren-9-one (TeNF) from chlorobenzene in the presence of pi -donor compounds yielded the chlorobenzene solvate, C16H4N6O8.C6H5Cl, and the bis(chlorobenzene) solvate, C13H4N4O9. 2C(6)H(5)Cl, respectively. Both structures comprise mixed stacks of twisted fluorene moieties interspersed with nearly parallel chlorobenzene molecules. Solvent-free crystals of DTeF and TeNF were obtained from pure chlorobenzene.
