Supramolecular architecture of crystals of 2-amino-1,1,4,5,6,7-hexafluoroindene-3-carbonitrile and its complex and polymorphic modifications of the complex of 2-amino-1,1,4,5,6,7-hexafluoro-3-trifluoroacetylindene with dioxane

Abstract

The molecular and crystal structure of 2-amino-1,1,4,5,6,7-hexafluoroindene-3-carbonitrile, its complex, and two polymorphic modifications of the complex of 2-amino-1,1,4,5,6,7-hexafluoro-3-trifluoroacetylindene with 1,4-dioxane were determined with X-ray diffraction analysis. The supramolecular architecture of the crystals was analyzed based on the interaction energies of molecular pairs calculated by the DFT (M06-2X/TZV) method using experimental crystal atomic coordinates.
