Synthesis and crystal structure of 3-(2-{3-[2-(2-oxooxazolidin-3-yl)eth-oxy]quinoxalin-2-yl-oxy}eth-yl)oxazolidin-2-one.

In the title compound, C18H20N4O6, 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.
