摘要
3-(2-吡嗪基)茚、9-(2-吡嗪基)芴和9-(2-吡啶基)芴分别与Ru3(CO)12在二甲苯或庚烷中加热回流,得到了3个新的三核簇合物1~3.通过元素分析、红外光谱、核磁共振氢谱对簇合物的结构进行了表征,并用X射线单晶衍射法测定了簇合物1的结构.结果表明:晶体属于三斜晶系,PT空间群,其晶胞参数a=0.932 9(3)nm,b=1.088 5(3)nm,c=1.197 0(3)nm,α=87.622(4)°,β=74.807(3)°,γ=78.951(4)°,V=1.151 3(6)nm^3,Z=2,Dc=2.156g/cm^3,μ=1.999mm-1,F(000)=716,R1=0.045 7,wR2=0.115 3.CCDC:937927.
The 3- (2-pyrazinyl) indene, 9- (2-pyrazinyl) fluorene and 9- (2-pyridyl) fluorene reacted with Ru3 (CO)~2 in refluxing xylene or heptane to give three trinuclear cluster compounds 1~3. Three new clus- ter compounds were characterized by IR, elemental analysis and 1HNMR spectra, respectively. The crystal structure of compound 1 was determined by X-ray single crystal diffraction. Crystal data:triclinic system, space group PT,a=0.932 9(3)nm,b=1.088 5(3)nm,c=1.197 0(3)nm,α=87.622(4)°,β=74.807(3)°,γ=78.951(4)°,V=1.151 3(6)nm^3,Z=2,Dc=2.156g/cm^3,μ=1.999mm-1,F(000)=716,R1=0.045 7,wR2=0.115 3.CCDC:937927..
