¹ Determined by DSC; ² DSC conditions: 2–8 mg of the compound; 40 °C for 10 min, then 10 °C/min to 250 °C, Crimped aluminum pan, N₂ (50 mL/min); ³ The authors reported this interval of decomposition temperatures; no T_d is reported for each compound; ⁴ Inflection point of the endothermic peak behavior; ⁵ DSC conditions: From −10 °C to T_max (depending on compound stability) then cooling from T_max to −10 °C at 10 °C/min, two heating-cooling cycles, hermetically sealed aluminum pan, N₂. ⁶ These data have been taken from Reference [17]. For DSC conditions see note 9; ⁷ TGA conditions: 5 °C/min to 400–500 °C, Alumina crucibles, N₂. ⁸ Td_5% ⁹ DSC conditions: From −50 °C to T_max (depending on compound stability), 10 °C/min; aluminum hermetically sealed pans, N₂; ¹⁰ DSC conditions: From −20 °C to T_max (depending on compound stability), two heating-cooling cycles, 5 °C/min, hermetically sealed aluminum pan, N₂.
