摘要
常温条件下合成了一个基于Anderson结构多阴离子和吗啉分子的多酸超分子标题化合物,通过X-射线单晶衍射、元素分析、红外光谱和热重对该化合物进行结构分析及性质表征。由单晶数据解析,该晶体属于三斜晶系,P-1空间群,a=0.793 54(4)nm,b=0.996 14(5)nm,c=1.370 98(7)nm,α=110.432 0(10)°,β=102.858 0(10)°,γ=90.590 0(10)°,V=0.985 48(9)nm3,Z=1,R1=0.035 2,wR_2=0.102 8。标题化合物中,带相反电荷的Anderson结构铝钼多阴离子和吗啉抗衡阳离子以及中性水分子通过静电引力结合,并交错排列形成稳定的单晶结构。光催化实验证明,标题化合物可以作为一种降解二甲酚橙的优良催化剂。
A new Anderson-type polyoxometalate [ H2N (CH2CH2)2O]3 [Al(OH)6Mo6O18]·5.5H2O has been synthesized and confirmed by single crystal X-ray diffraction, IR spectra, and Thermogravimetric analysis (TGA). Single-crystal X-ray diffraction data:triclinic space grnup P-1,a =0.793 54(4) nm,b =0.996 14(5) nm,c = 1.370 98(7) nm,α =110.432 0(10)°,β= 102. 858 0 (10)°, γ = 90. 590 0 (10)°, V = 0. 985 48 ( 9 ) nm^3 , Z = 1 , R1 = 0. 035 2, wR2 = 0. 102 8. X-ray diffraction indicated that protonated morpholine cation,isolated water molecules and Anderson-type [Al(OH) 6Mo6O18]^3- anion were linked together through electrostatic interactions and intermolecular forces. The title compound shows good photocatalytic activity toward xylenol orange.
