title: 2-(exo-tricyclo[5.2.1.0(2,6)]deca-4,8-dien-3-endo-yl)acetaldehyde 2,4-dinitrophenylhydrazone.
abstract: The six-membered ring of the norbornene moiety in the title compound, C(18)H(18)N(4)O(4), is in a slightly distorted boat conformation, and the two five-membered rings within it adopt envelope conformations. The structure is stabilized by inter- and intramolecular N[bond]H...O hydrogen bonds.
