The crystals of 1‐(2‐pyridymethyl)‐2,4,6‐triphenylpyridinium perchlorate are monoclinic, space group P 2 1 /b. The unit cell parameters are a = 18.941(5), b = 19.502(6), c = 15.135(5), y = 115.99°(2), Z = 8, d 0 = 1.31(3), d x = 1.319 g/cm 3 . The structure has been determined by direct methods and refined by block diagonal least squares to R 0 = 0.08 for 2520 reflections. The phenyl rings in both molecules (I) and (II) are planar. These rings are twisted with respect to the central pyridyl rings.
