Key Points

To investigate the synthesis and crystal structure of a novel oxazolidine compound.
Synthesize the compound with a specific chemical structure
Analyze the crystal structure using X-ray diffraction
Conduct Hirshfeld surface analysis for packing interactions
The oxazolidine rings exhibit different conformations: one is twisted and the other is a shallow envelope
Weak hydrogen bonds and π–π stacking interactions contribute to the three-dimensional structure
Hirshfeld surface analysis shows predominant contributions from H...H (48.4%) and H...O/O...H (29.1%) contacts

Abstract

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 interactions 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.
