title: FAIR-MOFs:A Comprehensive Database for Accelerating the Discovery and Synthesis of Metal-Organic Frameworks

description: Dataset Description

The following datasets constitute the FAIR-MOFs repository, which is  a comprehensive and highly curated collection of metal-organic frameworks (MOFs), associated ligands, metal clusters, porosities, formation energies, synthetic conditions, and other derived features. These files can be directly downloaded and used for machine learning, data mining, cheminformatics, and synthesis prediction tasks.
