N-(2,5-Dimeth­oxy­phen­yl)-6-nitro­quinazolin-4-amine

In the title mol­ecule, C(16)H(14)N(4)O(4), the quinazoline ring is substanti­ally planar (r.m.s. deviation = 0.0129 Å) and forms a dihedral angle of 2.73 (8)° with the benzene ring. The conformation of the mol­ecule is stabilized by an intra­molecular C—H⋯N hydrogen bond. In the crystal, mol­ecules...

Sumario:In the title mol­ecule, C(16)H(14)N(4)O(4), the quinazoline ring is substanti­ally planar (r.m.s. deviation = 0.0129 Å) and forms a dihedral angle of 2.73 (8)° with the benzene ring. The conformation of the mol­ecule is stabilized by an intra­molecular C—H⋯N hydrogen bond. In the crystal, mol­ecules are linked into chains running parallel to the b axis by C—H⋯O hydrogen bonds. In addition, π–π stacking is observed between dimethoxy-substituted and nitro-substituted benzene rings, with centroid–centroid distances in the range 3.6438 (10)–3.7148 (10) Å.
