techniques provide accurate information on the structure of the molecular complexes and the nature of the interactions involved. Here, we present the first example of a squaramide–nitratesalt. X-ray crystallography and theoretical studies show the important roles of anion–π and hydrogen-bondinginteractions in the crystal packing of this compound in relation to those found in the free squaramide solid structure
