Abstract

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.
