Synthesis,structure and fluorescence properties of a pyrazol-5-yl indole-3-carboxylate

以3-吲哚甲酸与1-苯基-3-甲基-5-吡唑啉酮为原料合成3-甲基-1-苯基吡唑-5-基-1H-吲哚-3-甲酸酯（3）,用IR、1 H NMR、热重分析、X-射线单晶衍射对化合物结构进行了表征,并对其荧光光谱进行了研究.X-射线单晶衍射结果表明：该晶体为斜方晶系,Pbca空间群,a=1.090 90（10）nm,b=1.618 93（14）nm,c=1.819 11（16）nm,α=β=γ=90.00°,V=3.212 7（5）nm3,Z=8,dC=1.312g/cm3,μ=0.088mm-1,F（000）=1 328.

3-methyl-1-phenyl-1 H-pyrazol-5-yl 1 H-indole-3-carboxylate（3）was synthesized by the reaction of 3-methyl-1-phenyl-2-pyrazolin-5-one with 3-indoleformic acid.The structure was characterized by IR,1 H NMR,X-ray and TGA.Its fluorescence property was also investigated.The results of structural analysis indicated that the crystal belong to the orthorhombic system,space group Pbca with a=1.090 90（10）nm,b=1.618 93（14）nm,c=1.819 11（16）nm,α=β=γ=90.00°,V =3.212 7（5）nm3,Z=8,DC=1.312 g/cm3,μ=0.088 mm-1,F（000）=1 328.
