A novel oxazole-5-one derivative 2-o-tolyl-4-(3-N,N-dimethylaminophenylmethylene)-oxazol-5-one (TDPO) C19H18N2O2 is synthesized and characterized and the crystal structure is determined by X-ray crystallography. TDPO is monoclinic in the P21/c space group. The molecule adopts the Z configuration. To enlighten the flexibility of TDPO, the sel ected torsion angle is varied fr om -180° to 180° in each 10° separately, and the molecular energy profile is calculated and analyzed by density functional calculations. In addition, Bader′s QTAIM analysis is performed to investigate the intramolecular weak interactions.
