Abstract

Computational methods were used to calculate the crystal lattice energy reflecting global interactions, pre- dominantly long-range electrostatic interactions between ions, as well as the energy of selected specific local C–H ... O, C–H ... π and π ... π interactions found in synthesized 7-(di- ethylamino)-2-(2-oxo-2 H -chromen-3-yl)chromenium per- chlorate, the structure of which was determined by X-ray crystallography. Local interactions occurring between specific sites of molecules, amounting to a few tens of kJ mol - 1 , most likely account for the mutual arrangement of molecular ions, whereas global ones, exceeding half-a- thousand kJ mol - 1 , are responsible for the thermodynamic stability of the compound investigated in the crystalline solid phase, whose potential applications are briefly outlined.
