Abstract: The title compound, [K(C₁₄H₂₀O₅)₂][Ni(C₃S₅)₂] or [K(benzo-15-crown-5)₂][Ni(dmit)₂], consists of K^I complex cations with benzo-15-crown-5 ligands and Ni^III complex anions with 4,5-dimercapto-1,3-dithiole-2-thione (dmit) ligands. The Ni^III atom is coordinated by four S atoms from two dmit ligands in a distorted square-planar geometry, while the K⁺ cation is coordinated by ten O atoms from two crown ether ligands.
