Diethyl 2-(acridin-9-ylmethylene)malonate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2001 The title compound, C21H19NO4, (II), is an acridine derivative with an angle of 68.30 (2)° between the aromatic ring system and the ethylene moiety. It is remarkable that (II) is isostructural with diethyl 2-(anthracen-9-ylmethylene)malonate, which bears a C atom at the position where in (II) an N atom is found.
