CrystalExplorer (CE) is a freeware designed to analysis the crystal structure with *.cif file format.

[1] CE is helpful to investigate different areas of solid-state chemistry such as Hirshfeld surface analysis, intermolecular interactions, polymorphism, effect of pressure and temperature on crystal structure, single-crystal to single-crystal reactions, analyzing the voids present in crystal, and structure-property relationships.

[3] CrystalExplorer launched as a graphical user interface which facilitates the visualization of interactions in molecular crystal structures.

[5] CrystalExplorer 2.1 designed for Mac OS X, Windows and Linux platforms for the analysis of crystal structures and can be used to investigate many areas of solid-state chemistry such as studying intermolecular interactions, polymorphism, the effects of pressure and temperature on crystal structures, single-crystal to single-crystal reactions, analyzing crystal voids, structure-property relationships,[6] isostructural compounds,[7] and calculate intermolecular interaction energies.

[8] Currently in 2020 September, there are more than 2000 research papers that cite CrystalExplorer software as per google scholar analysis.
