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

Abstract

In the title compound, C 23H 15N 3O 2, significant deviations from planarity are evidenced in the values of the dihedral angles formed between the aminobenzene 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 twodimensional array with a zigzag topology that stacks along the (1 0 2) plane.
