In the solid state, the title compound, C 25 H 16 Br 2 O 2 , shows significant deviations of the fluorene ring system from planarity. A layered hydrogen-bonded structure is formed that may serve as a model for the solid-state structure of phenol-functionalized polyfluorene.

## Abstract Novel spiro[fluorene‐9,4′‐(1′,2′,3′,4′‐tetrahydropyridine)]‐5′‐carbonitriles 6a‐c have been obtained from the reaction of __N__^1^,__N__^2^‐diarylacetamidines 1a‐c with (2,4,7‐trinitro‐9__H__‐fluoren‐9‐ylidene)propanedinitrile (2) in ethyl acetate solutions at ambient temperature for 6a
