Synthesis and structure of an arylselenenium(II) cation, [C₃₄H₄₁N₄Se⁺]₂[Hg(SeCN)₄]²⁻, based on a 5-tert-butyl-1,3-bis(1-pentyl-1H-benzimidazol-2-yl)benzene scaffold

Abstract

In [C34H41N4Se+]2[Hg(SeCN)4]2−, the aryl­selenenium cations, [C34H41N4Se]+, and [Hg(SeCN)4]2− anions are linked by C—H⋯N hydrogen bonds. In the cation, the geometry around the Se atom is T-shaped, resulting from the coordination of Se by the C atom of the central aromatic ring and the N atoms of the benzimidazolyl moieties.
