6-Ethyl-N-methyl-3-nitro-4-nitro­methyl-4H-chromen-2-amine

In the title compound, C(13)H(15)N(3)O(5), the O and N atoms of the nitro­methyl group and the methyl C atom of the ethyl group are disordered over two sets of sites with refined occupancies of 0.629 (7):0.371 (7) and 0.533 (8):0.467 (8), respectively. The dihydro­pyran ring has an extremely flatten...

Descripción
Sumario:In the title compound, C(13)H(15)N(3)O(5), the O and N atoms of the nitro­methyl group and the methyl C atom of the ethyl group are disordered over two sets of sites with refined occupancies of 0.629 (7):0.371 (7) and 0.533 (8):0.467 (8), respectively. The dihydro­pyran ring has an extremely flattened conformation. An intra­molecular N—H⋯O hydrogen bond occurs. In the crystal, pairs of N—H⋯O hydrogen bonds link mol­ecules, forming inversion dimers. In addition, weak inter­molecular C—H⋯O hydrogen bonds are also present.
