Abstract The anation and decomposition reaction of trans [CrF(H 2 O)(aa′) 2 ]S 2 O 6 [aa′ = ethylenediamine (en); 1,3-diaminepropane (tmd)] have been studied by means of ATD, TG and DSC techniques. The first and only perfectly defined step is the anation reaction forming the species cis [CrF(S 2 O 6 )(aa′) 2 ]. By means of DSC techniques, the enthalpies of reaction and the activation energies of both
摘要 反式[CrF(H 2 O)(aa') 2 ]S 2 O 6 [aa' =
乙二胺(en); 1,3-二胺
丙烷 (tmd)] 已通过
ATD、TG 和
DSC 技术进行了研究。第一个也是唯一一个完美定义的步骤是形成顺式 [CrF(S 2 O 6 )(aa') 2 ] 的阴离子反应。通过
DSC 技术,已经估计了反应焓和两种反应的活化能。所得产物的电子光谱表明顺式构型。第二步,在配合物完全分解之前,涉及顺式 [CrF(S 2 O 6 )(aa') 2 ] → 顺式 [CrF(SO 4 )(aa') 2 ] + SO 2 被分解反应污染.
