DOI: https://doi.org/10.15128/r2m613mx61c DATA & FILE OVERVIEW File Overview: Folder structure: TEM - contains transmission electron micrographs of samples in the paper as dm3 files (with some additional image files or EDS data). This is in two additional Zip files. PXRD - contains powder x-ray diffraction patterns as .xy data. ssNMR - contains ssNMR data bundle in native and processing files, as well as pdf images of all data collected, the readme in this folder gives file nomenclature. DLS - contains DLS data as excel format data. Infrared - contains infrared data as csv files. Except for solid state NMR files are saved to include the identifier in the form "ZIHXXX" (e.g. ZIH011), where the genesis of the samples is explained in the supporting information of the journal paper, or else they carry the descriptive names (parent Sil-1, Pd/Sil-1, Pd◈SH-Sil-1 or Pd◈MH-Sil-1 used in the paper). METHODOLOGICAL INFORMATION Description of methods used for collection/generation of data: The methods used to generate the data are described in the journal paper.
