Potassium cobaltinitrite K3[Co(NO2)6] has been synthesized by three methods. The crystalline products have been characterized by scanning electron microscopy, X-ray powder diffraction, IR spectros-copy, and thermal and sedimentation analyses. A comparative analysis of the synthetic methods has been carried out. The highest yield, the smallest particle size, and the highest purity of the product are attained by reacting potassium nitrite with cobalt nitrate in an acid medium in the same way as in the synthesis of sodium cobaltinitrite: 2CH3COOH + Co(NO3)2 + 7KNO2 → K3[Co(NO2)6]↓ + 2KNO3 + 2CH3COOK + NO↑ + H2O. All of the resulting potassium cobaltinitrite samples are hygroscopic. The water release and nitrite ion elimination temperature intervals have been determined.
