本文以气相色谱法为主要手段, 配合Mossbauer谱、红外光谱等结构分析方法, 研究了一系列一取代基五氰合铁(II)类配合物Na2[Fe(CN)5L]·mH2O及Na3[Fe(CN)5L']·nH2O(L=NO^+、N2H5^+、enH^+, L'=NH3、H2O、Py)的热分解反应。结果表明所有一取代五氰合铁(II)配合物热分解过程中都形成相同的中间化合物Na4[Fe(CN)6]和Fe2[Fe(CN)6], 各配合物热分解放出取代基L(L')的温度次序与L(L')在光谱化学序列中的次序一致。本文以亚硝基铁氰化钠为代表, 详细讨论了该系列配合物的热分解反应机理以及热稳定性的规律性。

The thermal decomposition of Na2Fe(CN)5L.mH2O (L = NO+, N2H5+, H2NCH2CH2NH3+) and Na3Fe(CN)5L'.nH2O (L' = NH3, H2O, py) was investigated by gas chromatog., Moessbauer and IR spectroscopy. The results showed that the same solid intermediate products of Na4[Fe(CN)6] and Fe2[Fe(CN)6] were produced. The temps. at which those complexes lost the ligand L(L') is in accordance with the spectrochem. series. Na2[Fe(CN)5NO].mH2O was used as an example to elucidate the mechanism of thermal decomposition and the relative thermal stability of various pentacyanoferrate(II) complexes.
