分离出N-稠合四苯基卟啉钌配合物的三种可能的异构体，Ru（NFTPp）Cl（CO）2（2a-c），并通过NMR、IR、CV、UV-vis-NIR吸收和X射线晶体学分析进行了充分表征。每个异构体是稳定的，在环境条件下和异构化α 2a-coccurred在升高的温度下，在溶液和固体状态，通过分子内旋转途径。2a-c的电子结构进行了详细的DFT研究，揭示了明显的差异之间的相互作用NFTPp配体和Ru-Cl部分。
Three possible isomers of N-fused tetraphenylporphyrin ruthenium complexes, Ru(NFTPp)Cl(CO)2(2a–c), were isolated and fully characterized by NMR, IR, CV, UV–vis-NIR absorption, and X-ray crystallographic analyses. Each isomer was stable at ambient conditions and isomerization among2a–coccurred at elevated temperature both in solution and in a solid state, through the intramolecular rotational pathways. Electronic structures of2a–cwere analyzed in detail by DFT study to reveal appreciable differences in the interaction between the NFTPp ligand and the Ru–Cl moiety.
