The title compound （C40H42N2） has been synthesized by the reaction of l-（l- naphthyl）-l-phenyl-3-chloropropylene and bis（4-（diethylamino） phenyl）methanone, and characterized by IR, ^1H NMR, MS and X-ray diffra...The title compound （C40H42N2） has been synthesized by the reaction of l-（l- naphthyl）-l-phenyl-3-chloropropylene and bis（4-（diethylamino） phenyl）methanone, and characterized by IR, ^1H NMR, MS and X-ray diffraction analysis. The crystal belongs to the monoclinic system, space group P21/c with a = 17.047（3）, b = 10.807（2）, c = 18.494（4） A, β = 105.727（4）°, V= 3279.4（11） A^3, Mr = 550.76, Z = 4, Dc = 1.115 g/cm^3,μ（MoKa） = 0.085 mm^-1, F（000） = 1184, the final R = 0.0625 and wR = 0.1384 for 2276 observed reflections （1 〉 2σ（I））. X-ray analysis reveals that the butadiene fragment adopts a planar cisiod conformation and makes a dihedral angel of 69.4（2）° with the naphthalene ring.展开更多
