Mechanochemical synthesis of PbF2 by high energy ball milling

Abstract Lead(II)-fluoride was successfully prepared by high energy ball milling and for comparison by classical thermal solid state chemical reaction. The influence of different starting materials, fluorinating agents and synthesis methods on the formation of the orthorhombic α -phase and the cubic β -phase was investigated. XRD analysis provided insight of which phase was formed under varying synthesis conditions. 19 F and 207 Pb MAS NMR measurements delivered an even further insight into the local structures. Additional simulations of the 19 F spectra were performed to identify the 19 F- 207 Pb coupling constants of the four-fold coordinated fluorine sites in both phases.
