What Is The Structure Of Silver Difluoride?

Silver difluoride (AgF2) is an inorganic compound composed of one silver cation (Ag+) and two fluoride anions (F-) held together by ionic bonds. The structure of AgF2 can be described as a three-dimensional network of corner-sharing octahedra, with each octahedron consisting of four fluorine atoms arranged in a square planar configuration around a central silver atom. The remaining two sites on the octahedron are occupied by two additional fluorine atoms that bridge to adjacent octahedra, linking the structure together. This results in a complex crystal lattice that has a tetragonal structure and belongs to the space group I4/mmm. The Ag-F bond length is approximately 1.99 Å, and the F-Ag-F bond angle is approximately 90 degrees. Overall, the structure of AgF2 is highly symmetrical due to its octahedral geometry, resulting in a high degree of stability and resistance to decomposition.
