2,5,11,14-Tetra­oxa-8-aza­dispiro­[13.4.0]nona­deca-15,17,19-triene

The title compound, C14H21NO4, has been synthesized from o-dihydroxy­benzene by a three-step reaction. There are two chemically equal but crystallographically independent mol­ecules in the asymmetric unit. The crystal packing is governed by C—H⋯O hydrogen bonds and C—H⋯π inter­actions, forming an infinite network
