Hs. Bengaard et al., Interaction between an oxygen and an alkynyl-carbon atom in 1-(2-nitrophenyl)-4-phenylbutadiyne, ACT CRYST C, 55, 1999, pp. 106-108
The title compound, C16H9NO2, Studied at 122 K shows a short 1,5 interactio
n between a nitro-O atom and an alkynyl-C atom. The atomic separation is 2.
636(2)Angstrom, and the dialkyne group is bent from linearity at this C ato
m only.
