摘要
首次报道了一种新的多金属氧酸盐化合物[(CH2)5NH2]3·PMo12O40]的合成与晶体结构.该晶体属三斜晶系,p1空间群.结晶学参数a=1.354 3(3)nm,b=1.838 5(3)nm,c=1.949 4(4)nm,β=89.85(10)°,V=1.742 3(6)nm3,Z=1,Dc=2.563 mg/cm3,F(000)=3334,最终偏离因子R1=0.0 695,wR2=0.143 8.在分子结构中,杂多阴离子仍保持完整的Keggin结构,12-钼磷酸阴离子和质子化的哌啶分子通过静电引力和氢键相互作用.
A novel polyoxometalate containing piperidine,formulated with [(CH2)5NH2]3·[PMo12O40] 1 was first synthesized and characterized by elemental analyses, IR and single crystal X-ray diffraction. X-ray analyses show that it consists of three protonated piperidine and one [PMo12O40] ~ connecting with each other via hydrogen-bonds.
