摘要：
The title compound has been synthesized and its crystal structure was determined by X-raycrystallographic method.The crystal is triclinic,space group P-1,with unit cell dimensions a=6.146(5),b=8.473(6),c=14.383(5)(?);a=77.47(4),β=82.84(4),γ=69.00(8)°and Z=2.Theresults obtained reveal that the molecule of the title compound keeps a long conjugative system in-volving C=C double bond,cyclopropane ring,carbonyl group and isoxazolinone ring and adopts alow energy conformation including s-trans of C=C double bond,s-cis of carbonyl group with respectto the three-membered ring and like-s-trans of carbonyl group with the carbonyl group within theheterocyclic moiety.
