In the title salt, bis-{[5- tert -butyl-1,3-bis-(1-pentyl-1 H -benzimidazol-2-yl)benzene]selenium} tetra-kis-(seleno-cyanato)-mercury, (C 34 H 41 N 4 Se) 2 [Hg(SeCN) 4 ], the aryl-selenenium cations, [C 34 H 41 N 4 Se] + , are linked through [Hg(SeCN) 4 ] 2- anions by C-H⋯N hydrogen bonds. In the cation, the geometry around the Se atom in the 5- tert -butyl-1,3-bis-(1-pentyl-1 H -benzimidazol-2-yl)benzene scaffold is T-shaped, resulting from the coordination of Se by the C atom of the central aromatic ring and the N atoms of both of the benzimidazole moieties. The trans Se-N bond lengths are almost equal [2.087 (3) and 2.099 (3) Å] and the Se-C bond length is 1.886 (3) Å. The N-Se-N angle is 159.29 (11)°. The geometry around the Hg II atom in the [Hg(SeCN) 4 ] 2- anion is distorted tetra-hedral, with Se-Hg-Se angles ranging from 88.78 (3) to 126.64 (2)°. In [Hg(SeCN) 4 ] 2- , the Hg-Se bonds are unsymmetrical [2.5972 (4) and 2.7242 (5) Å]. One of the pentyl substituents is disordered over two equivalent conformations, with occupancies of 0.852 (8) and 0.148 (8).
