X-ray diffraction was performed with a PANalytical Empyrean at 60 kV and 40 mA with Mo-Ka radiation of 0.713609 Å over a 2q range of 3-50°. Samples were mounted on a silicon zero background holder. A step size of 003581° and scan time of 37.575 s/step were used. We measured gas adsorption on a Micromeritics 3Flex. Brunauer-Emmett-Teller (BET) surface area was calculated from a nitrogen isotherm at 77 K. Ethane and ethylene isotherms were measured from 0.5-900 mmHg at 298 K. The MOF powder was activated at 120 °C under vacuum for 12 hours before each measurement. MOF elemental composition and bonding modes were analyzed based on X-ray photoelectron spectroscopy (XPS) using a PHI VersaProbe II X-ray Photoelectron Spectrometer (Physical Electronics, USA). The X-ray source had a power of 50 W and the beam spot size was 200 µm. Examining our literature-curated MOF dataset, some trends emerged in the composition of structures that were commonly investigated. By far, the most commonly occurring metals among the unique MOFs in the dataset are Cu (50 occurrences), Co (37), and Zn (32, Figure ). We note that this count represents all of the metal identities present across all structures, so structures with more than one metal type will be counted towards the total for multiple metal identity counts.
