RT journal article T1 Unusual reverse face-to-face stacking in propylene linked pyrazole system: perspective of organic materials A1 Kumar Rai, Sunil A1 Srivastava, Priyanka A1 Gupta, Hariom A1 Puerta Vizcaino, María del Carmen A1 Valerga Jiménez, Pedro Sixto A1 Kumar Tewari, Ashish A2 Ciencia de los Materiales e Ingeniería Metalúrgica y Química Inorgánica K1 2D NOESY K1 Density functional theory K1 Noncovalent interactions K1 Pyrazole K1 Single crystal X-ray diffraction K1 Transmission electron microscopy AB Flexible dimers 1, 2, and 3 of ‘‘pyrazole’’ derivatives linked with propylene spacer are synthesized and conformational stability in solid, solution, and gaseous states is studied through single crystal X-ray diffraction, 2D NOESY ,and DFT, respectively. 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.
