Input Dataset Used to Develop the Analytical Equations in "Physics-Informed Analytical Models for Interpretable and Deployable Hydrogen Storage Prediction in MOFs"

This record is the input dataset used to develop the analytical equations described in the manuscript“Physics-Informed Analytical Models for Interpretable and Deployable Hydrogen Storage Prediction in MOFs” It is a frozen snapshot of the data used for training/validation in the symbolic-regression workflow; it is not a product of the article. The dataset aggregates crystallographic descriptors for MOFs together with GCMC-derived usable hydrogen capacities under 77 K, 100→5 bar, enabling exact reproduction of equation-discovery and benchmarking steps (SISSO, PySR, AI Feynman, gplearn). Scope Systems: Metal–Organic Frameworks (MOFs) Rows: 88,400 MOFs (after quality filters) Targets: Usable gravimetric capacity UCg (wt.%) and usable volumetric capacity UCv (g H₂ L⁻¹) at 77 K, 100→5 bar Descriptors (7): single-crystal density ρc (g cm⁻³), gravimetric surface area Sg (m² g⁻¹), volumetric surface area Sv (m² cm⁻³), pore volume Vp (cm³ g⁻¹), void fraction Fv (–), largest included sphere Di (Å), largest free sphere Df (Å) Contents MOF_SR_Training_Dataset.csv — table with columns: ρc, Sg, Sv, Vp, Fv, Di, Df, UCg, UCv (and any included identifiers) Units (key fields): UCg: wt.% · UCv: g H₂ L⁻¹ · Sg: m² g⁻¹ · Sv: m² cm⁻³ · Vp: cm³ g⁻¹ · ρc: g cm⁻³ · Di, Df: Å Provenance & Use Curated for physics-informed symbolic regression and comparative benchmarking.
