文摘

Understanding the complex relationship between synthesis conditions, in particular temperature and composition, led to single crystals of the cryolite type phases Ag<sub>3sub>MoO<sub>3sub>F<sub>3sub> and Ag<sub>3sub>VO<sub>2sub>F<sub>4sub>. These crystals form in a reversible thermodynamic process from dissolved species when the solution is heated. Single crystal structural data reveal the Mo<sup>6+sup> cation distorted toward facially coordinated oxides for Ag<sub>3sub>MoO<sub>3sub>F<sub>3sub>, and the V<sup>5+sup> cation toward the edge of the cis-oxide positions for Ag<sub>3sub>VO<sub>2sub>F<sub>4sub>. Local ordering of oxide and fluoride ligands is observed for both structures.
