In the title compound, C 18 H 16 O 3 , the phenyl ring makes a dihedral angle of 59.67 (4) with the benzene ring of the chromanone unit. The molecular structure is stabilized by a weak intramolecular C-HÁ Á ÁO interaction and the crystal packing is stabilized by weak intermolecular C-HÁ Á ÁO and C-H

In the title compound, C 21 H 18 N 4 O 5 , the central vanillin group makes dihedral angles of 8.76 (13) and 62.38 (6) with its attached pyridine and nitrobenzene rings, respectively. The crystal packing is stabilized by N-HÁ Á ÁN hydrogen bonds and C-HÁ Á ÁO interactions, leading to an infinite net
