Source of material
All the reagents were purchased with analysis grade. In representative experiments, 5 ml HNO3 and 15 ml H2SO4 were dissolved in the solvent, then 14 g (50 mmol) bis (2-nitroimidazole-1-yl)ethidene were added at 293 K. The target compound was obtained by reaction at 348 K for 9 h. The raw product was dissolved in acetone and crystals of the title compound were obtained by slow evaporation at 293 K.
Experimental details
A suitable crystal was selected and mounted on a ‘Bruker APEX-II CCD’ diffractometer. Using Olex2 [2], the structure was solved with the XT [3] structure solution program and refined with the ShelXL [4] refinement package. All H atoms were positioned geometrically and treated as riding, with C–H bond 0.95 Å, and U iso(H) = 1.2U eq(C).
Comment
Ethan-1,2-diyl bridged nitrogen-containing ligands are semi-rigid which means that they behave between rigidity and flexibility. Chemists have drawed great attention to the synthesis of bridged diimidazoles, such as methane-bridged ones [5], [6], [7], [8].
The asymmetric unit of the title structure contains one target molecule and one acetone molecule (see the Figure). The nitroimidazole rings are almost flat, and the dihedral angle of the two nitroimidazole rings is 46.18°. In general, all bond lengths and angles are in the expected ranges in both molecules [9].
