| Abstract: | The crystal structure of ethyl bis(2,4-dinitrophenyl)acetate, determined by room temperature X-ray diffraction, shows that this crowded molecule contains two short intramolecular interactions between nitro oxygen atoms and electron deficient carbon atoms. One mimics an early stage of the nucleophilic addition to a carbonyl group (O...C, 2.730 Å), and the other mimics an early stage of a Michael reaction (O...C, 2.854 Å). Crystal data: C16H12N4O10, M
r = 420.29, a = 10.079(1), b = 11.139(1), c = 16.162(1) Å,  = 91.319(7)°, monoclinic, P21/c, Z = 4. |
