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)4 and 1-FSA, respectively). Their thermal properties and photoreactivities were investigated, and the linkage isomerization of the cations
硝化腈键异构化是固态金属配合物的光化学反应。为了定量说明晶体环境对该反应的影响,我们合成了阳离子铂(II)亚硝基络合物与Pt(NO 2)4 2–和(FSO 2)2 N –阴离子(1-Pt(NO 2)分别为4和1-FSA)。研究了它们的热性质和光反应性,以及阳离子和Pt(NO 2)4的键合异构化通过X射线结构分析观察到在180K的紫外线下的阴离子。1-Pt(NO 2)4和1-FSA中阳离子的异构化程度分别为49%和80%,Pt(NO 2)4阴离子的异构化程度为0-65%。该转化率与围绕NO 2配体的反应腔尺寸相关。
