Abstract
In the title compound, C(18)H(20)N(4)O(6), one of the oxazolidine rings adopts a twisted conformation and the other is a shallow envelope. In the crystal, weak C-H⋯O hydrogen bonds and π-π stacking inter-actions help to consolidate a three-dimensional architecture. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (48.4%) and H⋯O/O⋯H (29.1%) contacts.
