The crystal structure of (R,R)-4-bromo-2-{4-[4-bromo-1-(4-toluenesulfonyl)-1H-pyrrol-2-yl]-1,3-dinitrobutan-2-yl}-1-(4-toluenesulfonyl)-1H-pyrrole (1, C26H24Br2N4O8S2) is presented. The title compound was isolated in suitable yield as a by-product in our synthesis of geminal-dimethyl hydrodipyrrins. We observe an unforeseen enantiomeric resolution both in the bulk sample and the crystal of 1, with distinct C--H--O (Cmethyi--H--Onitro, Csp3--H--Osulfonyi) interactions observed in the enantiomers present, along with other interactions, namely C5-pyrrolyl--H-«-Osulfonyl, forming a polymer along the crystallographic caxis direction. Whiist pyrroiic fragments are weii documented in the iiterature, little data is found surrounding the 1,3-dinitrobutane scaffold. [ABSTRACT FROM AUTHOR]

The crystal structure of (R,R)-4-bromo-2-{4-[4-bromo-1-(4-toluenesulfonyl)-1H-pyrrol-2-yl]-1,3-dinitrobutan-2-yl|-1-(4-toluenesulfonyl)-1H-pyrrole (1, C26H24Br2N4O8S2) is presented. The title compound was isolated in suitable yield as a by-product in our synthesis of geminal-dimethyl hydrodipyrrins. We observe an unforeseen enantiomeric resolution both in the bulk sample and the crystal of 1, with distinct C--H⋯O (Cmethyl--H⋯Onitro, C...--H⋯Osulfonyl) interactions observed in the enantiomers present, along with other interactions, namely C5-pyrrolyl--H⋯Osulfonyl, forming a polymer along the crystallographic c-axis direction. Whilst pyrrolic fragments are well documented in the literature, little data is found surrounding the 1,3-dinitrobutane scaffold. [ABSTRACT FROM AUTHOR]
