摘要利用扩散法合成了K_3 NaH_1Nb_6O_(19)·11H_2O(1),借助IR、UV和X射线单晶衍射分析对这种化合物进行了结构和性质研究.其晶胞参数为:a=1.812 8(6)nm,b=1.790 8(6)nm,c=1.8130(7)nm,V=5.886(4)nm^3,Z=8,R_1[I>2σ(I)]=0.071 0,ωR_2[I>2σ(I)]=0.1857.化合物1由一个Lindqvist型[H_4Nb_6O_(19)]~1聚阴离子,三个K^4离子,一个Na^+离子和十一个H_2O组成. A new inorganic polyoxoniobate K3NaH4Nb6O19·11H2O（1） has been synthesized by the diffusion method and structurally characterized by infrared（IR）,ultraviolet（UV） and single crystal X-ray diffraction.Crystal data for 1,a = 1.812 8（6） nm,b= 1.790 8（6） nm,c= 1.813 0（7） nm,V = 5.886（4） nm3,Z = 8,R1[I2σ（I）]= 0.071 0,wR2[I2σ（I）]= 0.185 7.The structure analysis indicates that 1 consists of one Lindqvist[H4Nb6O19]4- polyoxoanion, three K~＋ cations,one Na~＋ cation and eleven crystal water molecules.
