The X -ray powder diffraction data of K3Sr3MoNb9O30 was first reported. The results show that K3Sr3MoNb9O30 belongs to tetragonal tungsten bronze (TTB) structure with unit cell parameters α=12. 4292(5) A . c = 3. 9338(3) A , and space group P4bm (100), z=1. The calculated and measured densities are 4. 897 g/crr3 and 4. 890 g/cm3, respectively.展开更多
