抄録

The title compound, 1,1′-ethane-1,2-diyl-dibenzimidazolium picrate, was crystallized in the triclinic system, space group P1 with a = 7.320(2)Å, b = 9.042(3)Å, c = 12.231(3)Å, α = 82.969(3)°, β = 81.734(3)°, γ = 68.090(3)°, V = 741.2(4)ų, Z = 1. The molecule of the title compound lies at the crystallographic center of symmetry, and an asymmetric unit in the unitcell contains half of the cation and one picrate ion. Also, the 1,1′-ethane-1,2-diyl-dibenzimidazolium cation units are linked by π-π interactions to give infinite two-dimensional (2-D) supramolecular layers, which are further linked by the intermolecular hydrogen bonds between the 1,1′-ethane-1,2-diyl-dibenzimidazolium cation and the picrate groups to form a three-dimensional (3-D) network supramolecule.
