3-Amino-1-(2H-1,3-benzodioxol-5-yl)-9,10-dihydro­phenanthrene-2,4-dicarbonitrile

In the title compound, C(23)H(15)N(3)O(2), significant deviations from planarity are evidenced in the values of the dihedral angles formed between the amino-benzene ring and the benzene rings of the 1,3-benzodioxole [65.38 (12)°] and 1,2-dihydro­naphthalene [26.27 (14)°] residues; the dioxole ring has an envelope conformation with the methyl­ene-C being the flap atom. The amino-H atoms form hydrogen bonds to one of the dioxole-O atoms and to one of the cyano-N atoms to generate a two-dimensional array with a zigzag topology that stacks along the ([Image: see text] 0 2) plane.
