Abstract The thermal decomposition of 26 complexes of the type [Co(en) 2 X 2 ]Y and cis -[Co(en) 2 (amine)X]Y 2 (where X is Cl or Br; Y is Cl, Br, I, NCS or NCO; amine is aniline, pyridine, β-picoline or o -anisidine, and en is ethylenediamine) has been studied by means of a derivatograph. The correlation between the content of water of crystallization, cis-trans isomerism and nature of the external
摘要 [Co(en) 2 X 2 ]Y 和顺式-[Co(en) 2 (胺)X]Y 2 (其中X为Cl或Br;Y为Cl、Br、 I、NCS 或 NCO;胺是苯胺、吡啶、β-甲基吡啶或邻茴香胺,en 是乙二胺)已通过衍生图进行了研究。讨论了结晶水含量、顺反异构与外球阴离子性质的相关性。顺式-[Co(en) 2 (胺)X]Y 2 型复合物热解的第一阶段是胺配体取代外部球体阴离子。从 TG 曲线可以推导出一些脱水和脱氨反应的动力学参数。
