1,1,3,3-Tetraethyl-5-nitroisoindoline

open access: yesIUCrData, 2019
The title compound, C16H24N2O2, previously obtained as a yellow oil, exhibits a rather low melting point close to room temperature 297–298 K). In the molecule, the isoindoline ring system is approximately planar and coplanar to the nitro group, forming a
