Mixed-stack structures of monovalent [Ni(dmit)2]- and planar M+(4,13-diaza-18-crown-6) (M+ = K+ or Rb+) supramolecular cation were obtained in the isostructural M+(4,13-diaza-18-crown-6)[Ni(dmit)2] salts. The mixed-stack structure decreases the effective π-π overlap of [Ni(dmit)2]- molecules, which results in the one-dimensional Heisenberg antiferromagnetic linear chain of S = 1/2 spins within the crystal.
