Abstract
The benzaldehyde nitrone moiety in the title molecule, N-benzylidene-4-fluoroaniline N-oxide, C 13 H 10 FNO, like that in N-(benzylidene)methylamine N-oxide [Bedford, Chaloner & Hitchcock (1991). Acta Cryst. C47, 2484-2485] approaches planarity [C benz -C benz -C=N-13(1)°cf176.0(2) and 6.8(2)°, respectively, in the methyl compound]. However, the p-fluorobenzene substituent is substantially twisted out of the molecular plane [C benz -C benz -N=C -42.8(8)°] in order to avoid a non-bonded O...H clash.
