Abstract
Crystallization of 2,4,5,7-tetranitro-9-(dicyanomethylene)fluorene [DTeF; s ystematic name: 2-(2,4,5,7-tetranitro-fluorene-9-ylidene)propanedinitrile] and 2,4,5,7-tetranitrofluoren-9-one (TeNF) from chlorobenzene in the presen ce of pi -donor compounds yielded the chlorobenzene solvate, C16H4N6O8.C6H5 Cl, and the bis(chlorobenzene) solvate, C13H4N4O9. 2C(6)H(5)Cl, respectivel y. Both structures comprise mixed stacks of twisted fluorene moieties inter spersed with nearly parallel chlorobenzene molecules. Solvent-free crystals of DTeF and TeNF were obtained from pure chlorobenzene.
