In the title compound, C~30~H~28~N~2~, each carbazole skeleton is essentially planar. The planes of the two carbazole ring systems are nearly parallel, with a dihedral angle of 2.33 (19)°. The crystal packing is stabilized only by van der Waals forces and weak C—H...π interactions.

Molecules of the title compound, C 12 H 26 N 4 S 2 , have 2/m symmetry. Intramolecular N-HÁ Á ÁN and N-HÁ Á ÁS hydrogen bonds are observed.
The asymmetric unit of the title complex, [Ni(C~11~H~29~N~5~)](ClO~4~)~2~, consists of an [Ni(C~11~H~29~N~5~)]^2+^ cation and two uncoordinated perchlorate anions. The Ni^II^ atom is five-coordinated in a slightly distorted square-pyramidal geometry, with four of the N atoms forming the basal plane
