硝基-硝基键异构化是众所周知的金属配合物在固体状态下的光化学反应。为了定量地阐明晶体环境对该反应的影响，我们合成了与Pt(NO2)42和（FSO2） 2n阴离子（分别为1-Pt(NO2)4和1- fsa）的阳离子铂（II）亚硝化配合物盐。研究了它们的热性能和光反应性，并通过x射线结构分析观察了阳离子与Pt(NO2)4阴离子在180 K紫外光照射下的连锁异构化反应。1-Pt(NO2)4和1- fsa4阳离子的异构化率分别为49%和80%，Pt(NO2)4阴离子的异构化率在0 ~ 65%之间。转化率与no2配体周围反应腔的大小有关。
Nitro–nitrito linkage isomerization is a well-known photochemical reaction of metal complexes in the solid state. To quantitatively elucidate the influence of the crystal environment on this reaction, we synthesized salts of a cationic platinum(II) nitrito complex with Pt(NO2)42–and (FSO2)2N–anions (1-Pt(NO2)4and1-FSA, respectively). Their thermal properties and photoreactivities were investigated, and the linkage isomerization of the cations and the Pt(NO2)4anion upon ultraviolet photoirradiation at 180 K was observed by X-ray structural analysis. The isomerization levels for the cations in1-Pt(NO2)4and1-FSAwere 49% and 80%, respectively, and that for the Pt(NO2)4anion was in the range of 0–65%. The conversion was correlated with the reaction cavity size surrounding the NO2ligands.
