Cover illustration: The compound C20H14N4 is a new polymorph of the previously reported structures, which were orthorhombic, space group Pbca [Bei et al. (2000). Acta Cryst. C56, 718-719] and monoclinic, space group P21/c [Dudd et al. (2003). Green Chem. 5, 187-192]. The crystal structures of two solvated forms of the same molecule have also been reported; the dimethylformamide monosolvate, monoclinic space group P21/n [Wu & Hu (2009). Acta Cryst. E65, o522] and the methanol monosolvate, triclinic space group P-1 [Su et al. (2011). Acta Cryst. E67, o90]. In all four crystal structures the 1,4-bis(1H-benzimidazol-2-yl)benzene molecules possess inversion symmetry. In the present monoclinic polymorph, space group P21/c, this is not the case, as the title compound crystallizes with two independent molecules in the asymmetric unit. See: Fu, Liang, Liu & Zhu [Acta Cryst. (2014). E70, o699].

Research communications

The first papers in this new format were published in July 2014. Research communications are longer papers with new text sections designed to help authors bring out the science behind their structure determinations. Figures are included in the published paper and, for the first time in Acta E, individual reports are not limited to single structure determinations. The Research communications format will make Acta E the natural home for structure determinations with interesting science to report.
