QTAIM analysis dataset for non-covalent interactions in furan clusters, Data in Brief, 40, 107766. https://doi.org/10.1016/j.jmgm.2021.1081022352-3409http://hdl.handle.net/11660/11356Furan clusters are very important to understand the dynam- ics and properties of the furan solvent. They can be used combined with quantum cluster equilibrium theory to theo- retically determine the thermodynamics properties of the fu- ran solvent. To understand the structures of the furan clus- ters, one needs to understand the non-covalent interactions that hold the furan molecules together. In this paper, we have provided the data necessary to understand the non-covalent interactions in furan clusters. Firstly, the structures of the furan clusters have been generated using classical molecu- lar dynamics as implemented in the ABCluster code. Sec- ondly, the generated structures have been fully optimized at the MP2/aug-cc-pVDZ level of theory. The optimized Carte- sian coordinates of all the investigated structures are re- ported in this work to enable further investigations of the furan clusters. These Cartesian coordinates will save compu- tational time for all further investigations involving the fu- ran clusters. Thirdly, to understand the nature of the non- covalent interactions in furan clusters, we have performed a quantum theory of atoms in molecule (QTAIM) analysis using AIMAll program. Using QTAIM, we have provided the critical points, bond paths and their related properties for all the in- vestigated structures. These data can be used to identify and classify the non-covalent interactions in furan clusters.enFuran clustersNon-covalent interactionsQTAIM analysisHeterocyclic moleculesBenzene clustersArticleAuthor(s)This is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/)
