Prussian blue analogues with formulae Ni₃[Co(CN)₆]₂·16H₂O(I), Cu₃[Co(CN)₆]₂·17H₂O(II), Ni₃[Fe(CN)₆]₂·15H₂O(III) and Cu₃[Fe(CN)₆]₂·13H₂O(IV) have been synthesized. The thermal decomposition of all complexes in oxidizing (air), reducing (hydrogen) and inert (argon) atmospheres was studied in the temperature range from 20 to 1000 °C. TG–DSC curves were obtained; analysis of solid thermolysis products was performed. It was established that the decomposition process of all the studied compounds in air ends up to 450–500 °C, and mass loss continues up to 1000 °C in argon. Solid products of thermolysis are oxides of central ions (NiO, CuO, Co₃O₄, Fe₃O₄) in air; mixtures of metals or Ni₃Fe (III) in argon; Ni and Co (I) and Ni₃Fe + Fe(III), and mixtures of Cu + Co (II) and Cu + Fe(IV) in hydrogen. Hexacyanocobaltates are reduced at lower temperatures and more fully than hexacyanoferrates under the same conditions.

具有分子式Ni ₃ [Co（CN）₆ ] ₂ ·16H ₂ O（I），Cu ₃ [Co（CN）₆ ] ₂ ·17H ₂ O（II），Ni ₃ [Fe（CN）₆ ]的普鲁士蓝类似物₂ ·15H ₂ O（III）和Cu ₃ [Fe（CN）₆ ] ₂ ·13H ₂ O（IV）已合成。在20至1000°C的温度范围内，研究了所有配合物在氧化（空气），还原（氢）和惰性（氩）气氛中的热分解。获得了TG-DSC曲线；进行了固体热解产物的分析。已经确定，所有研究的化合物在空气中的分解过程最终可达到450-500°C，而在氩气中质量损失将持续到1000°C。热分解的固体产物是空气中中心离子的氧化物（NiO，CuO，Co ₃ O ₄，Fe ₃ O ₄）；氩气中金属或Ni ₃ Fe（III）的混合物；Ni和Co（I）和Ni ₃ Fe + Fe（III）），以及在氢气中的Cu + Co（II）和Cu + Fe（IV）的混合物。在相同条件下，六氰合钴酸酯在较低温度下比六氰合铁酸酯还原得更充分。
