The 4:1 complex salt formed between 7,7,8,8-tetracyano-p-quinodimethane (TCNQ) and the N,N'-di(n-propyl)-4,4'-bipyridinium dication (DPrBP) is monoclinic, space group P2 1 /c, with a = 13.334(1), b = 25.954(3), c = 7.877(1) Å, β = 93.66(1)°. The structure was solved by the Patterson method and refined to R = 0.070 for 3277 unique reflections. The TCNQ moieties stack plane-to-plane, in stoichiometric groups of four, with a favourable exocyclic bond to quinonoid ring overlap of adjacent molecules and short interplanar spacings of 3.20 and 3.23 A between TCNQ (A)-TCNQ (A') and TCNQ (A)-TCNQ (B) respectively. TCNQ (A) makes the closet contact to the dication and the charge is partially localised on this molecule.
