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.
