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.}, publisher = {Springer}, keywords = {2D NOESY}, keywords = {Density functional theory}, keywords = {Noncovalent interactions}, keywords = {Pyrazole}, keywords = {Single crystal X-ray diffraction}, keywords = {Transmission electron microscopy}, title = {Unusual reverse face-to-face stacking in propylene linked pyrazole system: perspective of organic materials}, doi = {10.1007/s11224-014-0512-5}, author = {Kumar Rai, Sunil and Srivastava, Priyanka and Gupta, Hariom and Puerta Vizcaino, María del Carmen and Valerga Jiménez, Pedro Sixto and Kumar Tewari, Ashish}, }
