以溴乙酸、4-甲基吡啶、苯甲醛为原料,合成一种新型的苯乙烯吡啶盐,通过红外、元素分析、单晶X射线衍射等测试技术对化合物的结构进行表征.单晶X射线衍射结果表明,该化合物属于单斜晶系,P21空间群.晶胞参数:a=0.587 9(7)nm,b=0.852 3(10)nm,c=1.558 3(16)nm,β=91.925(7)°,Z=2,F(000)=211,最终R=0.050 9,wR=0.128 5.此外,还研究该化合物的紫外和荧光性质.

Abstract： A novel styryl pyridinium salt was synthesized and characterized by means of IR, elemental analysis and X - ray single crystal diffraction. The compound crystallized in the monoclinic space group P21 with a=0.5879（7）nm,b=0.8523（10）nm,c=1.5583（16）nm,β=91.925（7）°,Z=2,F（000）=211, and final R= 0. 050 9, wR = 0. 128 5. Meanwhile, the optical properties were also studied.
