The supramolecular (HOPD(+))(DB[18]crown-6) cation, in which HOPD(+) and DB[18]crown-6 are o-aminoanilinium and dibenzo[18]crown-6, respectively, was introduced into [Ni(dmit)(2)](-) salts (dmit(2-) = 2-thioxo-1,3-dithiole-4,5-dithiolate). Conformational polymorphs were observed as tetragonal (HOPD(+))(DB[18]crown-6)[Ni(dmit)(2)](-) (1) and monoclinic (HOPD(+))(DB[18]crown-6)[Ni(dmit)(2)](-) (2). The ammonium group of HOPD(+) in
