摘要 The target compound(C19H20ClNO)was structurally determined by single-crystal X-ray diffraction.The crystal is in monoclinic system,space group P21/n with a=9.2365(2),b=12.1241(3),c=14.9960(4)?,β=106.589(3)°,C19H20ClNO,Mr=313.81,Dc=1.295 g/cm^3,V=1609.42(7)?3,Z=4,F(000)=664,μ(MoKa)=2.097 mm-1,T=200(10)K,2813 independent reflections with 2533 observed ones(I>2σ(I)),R=0.0389 and wR=0.1057 with GOF=1.043(R=0.0423 and wR=0.1083 for all data).The 3,4-dihydroquinolin-2(1 H)-one moiety maintains thermodynamically stable trans configuration.The decomposition mechanism of compound 3 is complex by thermal analysis.
