4,4'-Di-tert-butyl-2,2'-dipyridinium dichloride.

ABSTRACT: In the title compound, C(18)H(26)N(2) (2+)·2Cl(-), the complete dication is generated by crystallographic inversion symmetry; both N atoms are protonated and engaged in strong and highly directional N-H?Cl hydrogen bonds. Additional weak C-H?Cl contacts promote the formation of a tape along ca. [110]. The crystal structure can be described by the parallel packing of these tapes. The crystal studied was a non-merohedral twin with twin law [-1 0 0, 0 -1 0, -0.887 0.179 1] and the final BASF parameter refining to 0.026?(2) .
