Detailed analysis of REPs revealed the lowest reaction energy path, which it is schematically shown in Figure \ref{442610}. The molecular structures of all species in Figure \ref{442610} as well as the corresponding transition states can be found in Figure \ref{324255}, which shows the 3D models interactively. The HTML code needed to embed the structures into this article is easily generated by ioChem-BD with a simple one-click process. For each structure we also provide a link for accessing the corresponding entry live in the ioChem-BD databases. For each entry, input files, optimized geometries, energies, vibrational frequencies, and other molecular properties are available.
