The 1,3-dioxin-4-one ring in the title compound, C(16)H(16)O(3), is in a half-boat conformation with the quaternary O-C(CH(3))(2)-O atom lying 0.546 (1) Å out of the plane defined by the remaining five atoms. The crystal structure is consolidated by C-H⋯O contacts that lead to supra-molecular layers.
متن کامل3-(4-Nitrobenzyl)-4H-chromen-4-one
In the title compound, C16H11NO4, the dihedral angle between the ten-membered chromen-4-one ring system (r.m.s. deviation = 0.0095 Å) and the benzene ring is 86.16 (5)°. In the crystal, mol-ecules are linked into a three-dimensional network by weak C-H⋯O hydrogen bonds. The crystal studied was a non-merohedral twin, with the minor twin component refining to 0.093 (1).

There are two independent mol-ecules in the the asymmetric unit of the title compound, C(11)H(14)N(2)O. The heterocyclic ring of the bicyclic system has a sofa conformation, with the C atom bearing the two methyl groups displaced by 0.541 (7) Å from the rest of the atoms of the ring [planar to within 0.064 (9) Å]. Mol-ecules are linked into centrosymmetric dimers via N-H⋯O hydrogen bonds.
