2-Amino-4-phenyl-56-dihydro­benzohquinoline-3-carbonitrile–3-amino-1-phenyl-910-dihydro­phenanthrene-24-dicarbonitrile (5/3)

摘要

The asymmetric unit of the 5:3 title co-crystal of 2-amino-4-phenyl-5,6-dihydro­benzo[h]quinoline-3-carbonitrile and 3-amino-1-phenyl-9,10-dihydro­phenanthrene-2,4-dicarbonitrile, 0.625C20H15N3.0.375C22H15N3, has the atoms of the fused-ring system and those of the amino, cyano and phenyl substitutents overlapped. The fused-ring system is buckled owing to the ethyl­ene linkage in the central ring, the two flanking aromatic rings being twisted by 20.1 (1)°. This ethyl­ene portion is disordered over two positions in a 1:1 ratio. The phenyl ring is twisted by 69.5 (1)° relative to the amino- and cyano-bearing aromatic ring. In the crystal, two mol­ecules are linked by an N—H⋯N hydrogen bond, generating a a helical chain along [010].
