title: 2-[(2,3,6,7-Tetra-hydro-1H,5H-benzo[ij]quinolizin-9-yl)methyl-ene]propane-dinitrile.
abstract: The π system of the title compound, known as julolidinemalononitrile, C(16)H(15)N(3), is nearly planar, with a 3.5 (1)° twist between the aromatic and dicyano-vinyl groups. The bond lengths indicate significant zwitterionic character in the ground state.
