Metal 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 BaCl 2 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 (O 3 C 3 N 3 ) 3– ion. The crystal structure of Ba 3 (O 3 C 3 N 3 ) 2 was refined by single‐crystal X‐ray diffraction, and the presence of cyanurate was verified by infrared spectroscopy.
