合成了一种Zn-K取代的夹心型锑钨酸盐Na9[Zn_3K_3(H_2O)_9][B-α-SbW_9O_(33)]_2·44 H_2O(1),并借助元素分析、红外光谱和X射线单晶衍射等方法对其进行了表征.标题化合物属于单斜晶系,C2/c空间群,晶胞参数:a=1.399 93(12)nm,b=2.317 6(2)nm,c=3.208 8(3)nm,β=98.804 0(10)°,V=10.288 0(15)nm~3,Z=4,D c=3.930 g/cm~3,GOOF=1.026,R_1=0.043 6,wR_2=0.103 5.X射线单晶衍射结构分析表明,化合物1分子结构由2个三缺位锑钨构筑块[B-α-Sb W9O33]9-通过12个缺位氧原子与1个六边形锌钾簇[Zn_3K_3(H_2O)_9]~(9+)相连而成.光催化结果表明,化合物1在一定程度上可以抑制偶氮荧光桃红的光降解.
A Zn-K substituted sandwich antimony tungstate Na9 [Zn_3K_3 (H_2O) _9] [B-α-SbW_9O_ (33)] _2 · 44 H_2O was synthesized and characterized by means of elemental analysis, IR and X Ray diffraction, etc. The title compound belongs to the monoclinic space group C2 / c with unit cell parameters of a = 1.399 93 (12) nm and b = 2.317 6 (2) nm, c = 3.208 8 (3) nm, β = 98.804 0 (10) °, V = 10.288 0 (15) nm~3, Z = 4, D c = 3.930 g / cm~3, GOOF = 1.026, R_1 = 0.043 6, wR_2 = 0.103 5. X-ray single crystal diffraction structure analysis showed that the molecular structure of compound 1 consisted of two [3-vacancy antimony tungsten building blocks [B-α-Sb W9O33] 9- with 12 oxygen vacancies and one hexagon (Zn_3K_3 (H_2O) _9] ~ (9+) .Photocatalytic results showed that compound 1 could inhibit the photodegradation of azo-fluorescing rosin to a certain extent.
