A four-step pipeline from raw XRD data to MOF identification against 138,158 reference structures
Upload XRD data files in any of 13 formats (CSV, Excel, XY, XRDML, UDF, JCP, X00, ASC, CIF, DAT, TXT, RAW, image) — no format conversion needed.
Choose your MOF's metal node(s) from the interactive periodic table. The engine filters 138,158 references to chemically relevant matches only.
Peaks found via local maxima detection. d-spacing computed via Bragg's law. MOF validity rule enforced: sharp peaks (FWHM < 0.3°) below 15° 2θ are required.
Peaks matched against 138,158 MOF structures from CSD, CoRE MOF, QMOF, and hMOF databases (±0.25° tolerance). Top 10 matches returned with confidence scores.
The reference database contains 138,158 MOF structures with simulated XRD fingerprints, compiled from seven public crystallographic databases: the Cambridge Structural Database (CSD) MOF subset, CoRE MOF 2019 & 2024, CoRE MOF 2014, the QMOF database (DFT-optimised), the hypothetical MOF (hMOF) library (51,163 structures), and the Northwestern mofdb.
Each structure has simulated 2θ peak positions (Cu Kα, λ = 1.5406 Å), primary d-spacings, unit cell parameters (a, b, c, α, β, γ), space group, metal node identity, and cell volume. The CSD-derived subset of 35,216 structures additionally includes DDEC6 partial charges and class labels.
A Random Forest classifier trained on structural features achieves 98.55% classification accuracy (AUC = 0.982) in distinguishing true MOFs, charge-reconstructed variants, and non-MOF structures. DDEC6 anomaly analysis reveals that 61.7% of charge-reconstructed CSD variants carry anomalous partial charges — a finding relevant to molecular simulation and machine learning force field development.
All MOF-validity criteria are enforced scientifically: patterns must show sharp peaks (FWHM < 0.3°) below 15° 2θ to be confirmed as MOF. Broad or high-angle-only patterns are correctly classified as non-MOF.
