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.

Mo / P比率对尺寸的影响：三种新型钼磷酸盐的合成，结构和性质。

含Mo（VI）的磷酸盐广泛用于催化剂，离子电池和非线性光学（NLO）晶体。但是，很少有策略可以有效地指导含Mo（VI）的磷酸盐的合成。本文通过调节Mo / P比例成功地合成了三种不同尺寸的新型含Mo（VI）的磷酸盐Cs3Mo12PO40，LiK（MoPO6）2和Sr（MoPO6）2。有趣的是，Cs3Mo12PO40是经典的Keggin型多金属氧酸盐，由零维（0D）[Mo12PO40] 3-簇组成，而LiK（MoPO6）2和Sr（MoPO6）2具有三维（3D）[MoO2O4P]∞框架， MoO6八面体和PO4四面体的比例为1/1。含Mo（VI）的磷酸酯的详细结构比较表明，Mo / P比对结构尺寸具有重大影响。进一步，
