Open Molecular Crystals 2025(OMC25)dataset
收藏资源简介:
OMC25数据集是一个包含超过2700万分子晶体结构的集合,每个单元细胞包含12种元素和最多300个原子。该数据集是从230,000多个随机生成的分子晶体结构的色散包容密度泛函理论(DFT)松弛轨迹中生成的,这些分子晶体结构由大约50,000个有机分子组成。OMC25涵盖了能够形成不同分子间相互作用和各种晶体堆积模式的多种化学化合物。数据集的创建过程包括从OE62数据集中采样分子结构,使用Genarris 3.0软件生成随机分子晶体结构,并进行结构松弛。OMC25数据集旨在解决分子晶体结构预测和性质预测的问题,为材料研究提供有价值的数据资源。
OMC25 dataset is a collection of over 27 million molecular crystal structures, each unit cell containing 12 distinct chemical elements and up to 300 atoms. This dataset is generated from dispersion-corrected density functional theory (DFT) relaxed trajectories of more than 230,000 randomly generated molecular crystal structures, which are constructed using approximately 50,000 organic molecules. OMC25 covers a wide range of chemical compounds capable of forming diverse intermolecular interactions and various crystal packing motifs. The development process of OMC25 involves sampling molecular structures from the OE62 dataset, generating random molecular crystal structures with Genarris 3.0 software, and conducting structural relaxation. The OMC25 dataset is intended to address the challenges of molecular crystal structure prediction and property prediction, serving as a valuable data resource for materials research.
