Abstract:
Mo(VI)-containing phosphates are widely used in catalyses, ion batteries, and nonlinear optical (NLO) crystals. However, few strategies can effectively guide the syntheses of the Mo(VI)-containing phosphates. In this paper, three new Mo(VI)-containing phosphates, Cs3Mo12PO40, LiK(MoPO6)2, and Sr(MoPO6)2, with different dimensions have been successfully synthesized by adjusting the Mo/P ratios. Interestingly, Cs3Mo12PO40 is a classic Keggin-type polyoxometalate composed of zero-dimensional (0D) [Mo12PO40]3- clusters, whereas LiK(MoPO6)2 and Sr(MoPO6)2 have three-dimensional (3D) [MoO2O4P]∞ frameworks consisting of MoO6 octahedra and PO4 tetrahedra in a 1/1 ratio. Detailed structural comparisons of Mo(VI)-containig phosphates indicate that the Mo/P ratios have a significant effect on the structural dimensions. Further, the optical properties and thermal stabilities of Cs3Mo12PO40, LiK(MoPO6)2, and Sr(MoPO6)2 are also determined.

Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
