Abstract
The title compound 8-(2,3-dimethoxyphenyl)-10,11,12,13-tetrahydro-9H-benzo[f]-cyclohepta[c]quinoline(C26H25NO2,Mr=383.47) was synthesized and characterized by IR,1H NMR,13C NMR and elemental analysis.The crystal belongs to triclinic,space group P1 with a= 8.1490(16),b=9.2550(19),c=14.373(3) ,α=86.96(3),β=89.66(3),γ=70.32(3)°,Z=2,V=1019.2(4) 3,Dc=1.250 g·cm-3,μ(MoKα)=0.078 mm-1,F(000)=408,the final R=0.0555 and wR=0.1240 for 2228 observed reflections(Ⅰ 2σ(Ⅰ)).X-ray analysis reveals that the seven-numbered ring is slightly similar to a six-numbered ring,forming the chair-like conformation.The four rings(Ⅰ,Ⅱ,Ⅲ and Ⅳ) in the benzo[f]cyclohepta[c]quinoline moiety form a screw structure.
