The dataset contains 24,157 silica inherent structures with a wide range of thermodynamic stabilities. The structures are generated by the replica exchange molecular dynamics and the melt-quenching molecular dynamics simulations with the BKS potential. The enthalpies and the structural features (covering density, coordination defects, pair distribution functions, S(q), rings, Si-O-Si bond angles, and torsion angles) of these structures are provided.
