The novel metal cyanurates LiSr(O3C3N3) and Li3Sr2F(O3C3N3)2 were prepared by exothermic solid state metathesis reactions and characterized by single crystal X-ray diffraction. Crystalline powders were prepared by reactions of alkali earth halides (SrCl2 and SrF2) with Li(OCN) in 1 : 3 molar ratios, at 450 and 575 °C. The reaction with chloride yielded LiSr(O3C3N3), and the reaction starting from the
