Article abstract of DOI:10.1016/0022-4596(86)90245-8

Based on structural, morphological, and thermoanalytical investigations the structural reaction mechanism including topotactic relations and the respective phase boundary process controlled macroscopic reaction mechanism of the thermal decomposition of single crystalline Ni(SCN)//2(C//5H//5N)//2 to Ni(SCN)//2 is presented. From the results obtained and from the comparison with further decomposition processes of model compounds, a general approach for the evaluation of specific kinetic parameters, in particular of direction dependent rate constants of solid state decompositions governed by phase boundary processes is derived.
