Abstract

The crystals of M⁺(15-crown-5)₂[Ni(dmit)₂] (M⁺ = K⁺ (1), Rb⁺ (2) and NH₄ ⁺ (3)) were prepared. In the crystal, M⁺ and 15-crown-5 formed a barrel-shape supramolecular cation structure, which filled the space between the [Ni(dmit)₂]^- layers. The [Ni(dmit) ₂]^- formed the π - π dimers which were connected through the side-by-side S ∼ S contacts. The interactions between [Ni(dmit)₂]^- within the dimer were not strong enough and the crystals showed Curie-Weiss magnetic susceptibility with the Weiss temperature θ of -3.8, -2.8 and -3.2 K for the salts 1, 2 and 3, respectively.
