AbstractMetal cyanurate compounds were prepared by means of solid‐state metathesis reactions between a metal halide and an alkali cyanurate. Following this procedure, a mixture of BaCl2 and K(OCN) was heated in a fused silica tube at 575 °C to yield highly crystalline barium cyanurate. This reaction was analyzed by differential scanning calorimetry (DSC) measurements and involves a cyclotrimerization of cyanate ions to yield the cyclic cyanurate (O3C3N3)3– ion. The crystal structure of Ba3(O3C3N3)2 was refined by single‐crystal X‐ray diffraction, and the presence of cyanurate was verified by infrared spectroscopy.
