Crystal structure of 2-[12-methyl-14-phenyl-10,13,14,16-tetra­aza­tetra­cyclo[7.7.0.0^2,7.0^11,15]hexa­deca-1(16),2,4,6,9,11(15),12-heptaen-8-yl­idene]propandi­nitrile

In the title mol­ecule, C₂₂H₁₂N₆, the fused tetracyclic core shows a small lengthwise twist as indicated by the dihedral of 2.7 (2)° between the outer rings. In the crystal, mol­ecules stack along the b-axis direction via offset π-stacking [centroid–centroid distances = 3.5282 (13) and 3.5597 (14) Å] with the stacks weakly associated through C—H...N hydrogen bonds. The phenyl ring is rotationally disordered over two orientations with an occupancy ratio of 0.516 (4):0.484 (4).

Crystal structure of (E)-4-{[2-(2,4-di­nitro­phen­yl)hydrazin-1-yl­idene]meth­yl}-3-methyl-1-phenyl-5-(1H-pyrrol-1-yl)-1H-pyrazole

The title compound, C₂₁H₁₇N₇O₄, is in an `extended' conformation aided by an intra­molecular N—H...O hydrogen bond. The pyrazole ring makes dihedral angles of 29.17 (6), 65.47 (4) and 9.91 (7)°, respectively, with the phenyl, pyrrole and benzene rings. In the crystal, mol­ecules are connected by pairs of N—H...O and C—H...O hydrogen bonds, forming inversion dimers which associate into ribbons running along the b axis through complementary C—H...O inter­actions.
