Structural characterization and DFT studies of the highly disordered compound 2-phenyl-4-[4-(1,4,7,10-tetraoxa-13-azacyclopentadecyl)benzylidene]-5-oxazolone

In this study, the crystal and molecular structure of the compound 2-phenyl-4-[4-(1,4,7,10-tetraoxa-13-azacyclopentadecyl)benzylidene]-5-oxazolone was determined by the single-crystal X-ray diffraction method. The molecular structure of the compound consists of a N-phenyl-(aza-15-crown-5) moiety connected to the oxazol-5-one ring. A phenyl group is also linked to the oxazol-5-one fragment. Crystal structure is stabilized by C–H？？？O type intermolecular hydrogen bonds, C–H？？？O type intramolecular interaction and pi？？？pi interactions. Theoretical studies such as molecular geometry, frontier molecular orbitals and molecular electrostatic potential were performed using the Density Functional Theory (DFT) method B3LYP/6-311G(d,p) basis set. Geometric parameters were compared with the experimental data and the compatibility was observed
