2-Amino-4-(3,4-dimeth-oxy-phen-yl)-5,6-dihydro-benzo[h]quinoline-3-carbo-nitrile-3-amino-1-(3,4-dimeth-oxy-phen-yl)-9,10-dihydro-phenanthrene-2,4-dicarbonitrile (1/19).

ABSTRACT: The asymmetric unit of the 1:19 title co-crystal of 2-amino-4-(3,4-dimeth-oxy-phen-yl)-5,6-dihydro-benzo[h]quinoline-3-carbo-nitrile and 3-amino-1-(3,4-dimeth-oxy-phen-yl)-9,10-dihydro-phenanthrene-2,4-dicarbonitrile, 0.05C(22)H(19)N(3)O(2)·0.95C(24)H(19)N(3)O(2), has the atoms of the fused-ring system and those of the amino, cyano and dimeth-oxy-phenyl substitutents overlapped. The fused-ring system is buckled owing to the ethyl-ene linkage in the central ring with the two flanking aromatic rings being twisted by 31.9?(1)°. The ring of the dimeth-oxy-phenyl substituent is twisted by 72.4?(1)° relative to the amino- and cyano-bearing aromatic ring. In the crystal, mol-ecules are linked by duplex amine N-H?O(meth-oxy) hydrogen bonds in a cyclic association [graph-set R(2) (2)(7)], generating a helical chain structure extending along [201].
