The hexamethylenediammonium ions lie on centres of symmetry and adopt a planar zigzag configuration. The two carboxyl groups of the phthalate ion are twisted by 48.8(3)° in the same sense from the plane of the six-membered ring. The packing arrangement involves spatial segregation of polar and non-polar regions of the molecule s into alternating layers perpendi...
