The title compound [BrBzPy][TCNQ] (BrBzPy+=1-(4-bromobenzyl)pyridinium cation, TCNQ- = 7,7,8,8-tetracyanoquinodimethanide anion) was synthesized by the reaction of [BrBzPy]Br and LiTCNQ in ethanol solution and its structure was determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group P21/c with a = 14.067(3), b = 7.3089(14), c = 23.796(4), β = 122.011(9)o, V = 2074.6(7) 3, Z = 4, C24H15BrN5, Mr = 453.32, Dc = 1.451 g/cm3, μ = 2.002 mm-1, S = 1.047, F(000) = 916, R = 0.0398 and wR = 0.0921. The most prominent structural features are the completely segregated stacking columns of the TCNQ- anions and [BrBzPy]+ cations. In a TCNQ column, the centroid-to-centroid distances of the neighboring anions of TCNQ are 3.2693 and 4.9464 , respectively.
