Synthesis and characteristics of a new three-dimensional molybdoantimonate Na4Sb12Mo5O35

A novel three-dimensional compound of Na4Sb12Mo5O35 has been synthesized by hydrothermal methods and structurally characterized by X-ray crystallography. It crystallizes in the triclinic system space group image with image, image, image, image, image, image, image, image, image, image for 7364 unique reflections with image. The molecular structure is built up of Mo6O21, MoO4 units, and cage-like units that contain 12 Sb atoms. IR, UV–Vis DRIS (Ultraviolet–Visible Diffuse Reflection Integral Spectrum), fluorescent spectra, and the thermogravimetric analysis of this compound were investigated.
