Crystal and molecular structure of 2,2’-(quinoxaline-2,3-diyl)dipyridinium dinitrate (H2 L)(NO3)2

The crystal structure of 2,2’-(quinoxaline-2,3-diyl)dipyridinium dinitrate (Н2L)(NO3)2 is studied by X-ray diffraction (T = 150 K, R1 = 0.0467). The H2L2+ cation is located on the twofold rotation axis and connected with two NO3 − anions by strong N–H···O hydrogen bonds. Planar quinoxaline fragments of cations form stacks with the interplanar spacing of 3.308 Å. The structure of the diprotonated H2L2+ cation is compared with those of the monoprotonated H2L2+ cation and neutral L molecule. © 2016, Pleiades Publishing, Inc.
