Conclusions The following conclusions may be derived from this study:(1) X-ray crystallographic work indicates that 1, Zdiphenyl-3-nitrocyclopropene exists as the bisected conformer in the solid state. Ab initio calculations on 3-nitrocyclopropene indicate that this is true for the gas phase as well.(2) The ring bond lengths (long C (l)-C (2), short C (l)-C (3)) and especially the long CN bond length are anomalous for a strong? r-acceptor such as ...
