Based on the careful structural analysis with two-dimensional (2D) NMR and x-ray diffraction, we have confirmed that the reported core structure, 8-oxo-8H-acenaphtho[1,2-b]pyrrol-9-carbonitril, was wrong. It should be corrected as 1-oxo-1H-phenalene-2,3-dicarbonitrile (1). Below we show a scheme about the comparison of the corrected structure with the wrongly assigned structure reported in the 2005 paper.



The following 2D NMR spectra provide direct evidences to support the structural characterization of 1:
