The crystal of the title compound, C(13)H(12)N(2)O(6), contains a bifurcated intra-molecular hydrogen bond between the N-H group and one of the O atoms from both the nitro group and the dioxane-4,6-dione moiety. In addition, mol-ecules are linked by a series of inter-molecular C-H⋯O secondary inter-actions. The dihedral angles between the benzene ring and the nitro group and the conjugated part...

There are two unique mol-ecules in the asymmetric unit of the title compound, C(17)H(15)NO(4), which are linked into chains via inter-molecular N-H⋯O and C-H⋯O inter-actions; the chains are linked via weak C-H⋯O inter-actions, forming a parallel sheet structure. The molecule is approximately planar, with dihedral angles of 19.91 (4) and 11.06 (4)° between the naphthyl ring and the amino-methyl-...

The asymmetric unit of the title compound, C13H11NO6, contains two mol-ecules in both of which the six-membered 1,3-dioxane-4,6-dione ring shows a screw-boat conformation. The dihedral angles between the best planes through the six-membered rings are 47.8 (2) and 49.8 (2)°. In the crystal, C-H⋯O inter-actions link the mol-ecules, building a supramolecular sheet parallel to the c axis.
