"The title heterocyclic compound, C14H15N3O3, is a new synthetic molecule containing oxazolidine and quinoxaline rings. It is built up from two fused six-membered rings linked to a five-membered oxazolidin-2-one ring by a C-2 chain," scientists in Rabat, Morocco report.
"Both ring systems are essentially planar [maximum deviation = 0.894 (3) angstrom, r.m.s. deviation = 0.0043 angstrom]. The structure is held together by van der Waals forces [electrostatic interactions between dipoles, O center dot center dot center dot C = 3.002 (2) angstrom] between molecules and by weak pi-pi stacking between symmetry-related molecules, with an interplanar distance of 3.579 ...
