Abstract: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.
Keywords:polyoxoanion  polyoxoniobate  diffusion method  crystal structure
