title: 2,2'-(Butane-1,4-di-yl)diisoquinolinium tetra-chloridozincate(II).
abstract: The crystal of the title compound, (C(22)H(22)N(2))[ZnCl(4)], consists of 2,2'-(butane-1,4-di-yl)diisoquinolinium organic cations and [ZnCl(4)](2-) complex anions. The cation is located across a twofold axis and the Zn(II) atom of the anion is located on the other twofold axis. The centroid-centroid distance between parallel pyridine rings of neighboring mol-ecules is 3.699 (3) Å, but the face-to-face separation of 3.601 (3) Å suggests there is no significant π-π stacking in the crystal structure.
