The thermal decomposition of the complexes Ni(SCN)2(fp)4·2H2O (I), Ni(SCN)2(mfp)4 (II) and Ni(SCN)2(dmfp)3 (III) (where fp=furo[3,2-c]pyridine, mfp=2-methylfuro[3,2-c]pyridine and dmfp=2,3-dimethylfuro[3,2-c]pyridine) have been investigated in dynamic air from room temperature to 1000°C by means of TG, DTG and DTA. The chemical composition of the complexes, solid intermediates and the resultant products of thermolysis have been identified by means of elemental analysis and complexometric titration. The results revealed that NiO was left as residue at the end of the thermal degradation experiments. IR data suggested that fp, mfp and dmfp were coordinated to Ni(II) through the N atom of the respective heterocyclic ring.
通过 TG、DTG 和 DTG 等方法研究了 Ni(SCN)2(fp)4-2H2O (I)、Ni(SCN)2(mfp)4 (II) 和 Ni(SCN)2(dmfp)3 (III) 复合物(其中 fp=furo[3,2-c]pyridine, mfp=2-methylfuro[3、2-c]
吡啶和 dmfp=
2,3-二甲基呋喃并[3,2-c]吡啶)在室温至 1000°C 的动态空气中通过 TG、DTG 和 DTA 进行了研究。通过元素分析和络合滴定法确定了络合物、固体中间产物和热解产物的
化学成分。结果表明,在热降解实验结束时,NiO 成为了残留物。红外数据表明,fp、mfp 和 dmfp 通过各自杂环的 N 原子与 Ni(II) 配位。
