Crystal Growth of Ag3MOxF6−x(M= V,x= 2;M= Mo,x= 3)

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