Experimental

Compound (I) was obtained in trace amounts as a by-product in the treatment of 3,3 H -bis(4-¯uorophenyl)-[2,2 H ]biindenyl-1,1 H -dione with Zn and ZnCl 2 in aqueous tetrahydrofuran to obtain 3,3

biindenyliden-1-one (7% yield; Tanaka et al., 2003). The

The title compound, C 19 H 14 F 3 N 3 O 3 S, is built up from pyrazolinone, thiophene, phenyl rings and tri¯uoropropanedicarbonyl moieties. Examination of the ÐC N and ÐC O bond lengths reveals that there is no electron delocalization over the molecule.
