The folded conformation of compound 2 is stable in all three states and X-ray diffraction evince that molecule is intramolecularly stacked in reverse face-to-face manner. TEM image of compound 2 exhibits rigid hollow nanospikes with high tendency to form agglomerates. %K 2D NOESY %K Density functional theory %K Noncovalent interactions %K Pyrazole %K Single crystal X-ray diffraction %K Transmission electron microscopy %~ Universidad de Cádiz
