Thermal behavior of binary complex сompounds сontaining the hexacyanoferrate anion

The thermal behavior of compounds with the general formula [MA 6 ] x [Fe(CN) 6 ] y (M = Со, Cu, Ni, A = NH 3 , 1/2 C 3 H 10 N 2 ) in air, argon, nitrogen, and hydrogen at temperatures between 20 to 1000°C was studied. The study involved measurement of TG–DSC–DTG curves and analysis of solid and gase...

Summary:The thermal behavior of compounds with the general formula [MA 6 ] x [Fe(CN) 6 ] y (M = Со, Cu, Ni, A = NH 3 , 1/2 C 3 H 10 N 2 ) in air, argon, nitrogen, and hydrogen at temperatures between 20 to 1000°C was studied. The study involved measurement of TG–DSC–DTG curves and analysis of solid and gaseous thermolysis products. It was found that the process is not affected by the nature of the atmosphere up to about 200°C. The coordinated cyanide ion partially releases as hydrogen cyanide. The destruction of diamines forms NH 3 , and a large amount of carbon remains in the solid phase.
