Abstract One metalorganic complex [K( cis‐syn‐cis‐ dicyclohexyl‐18‐crown‐6)] 2 [Cu(mnt) 2 ] (mnt = maleonitriledithiolate) has been obtained by the reaction of dicyclohexyl‐18‐crown‐6 with K 2 mnt and CuCl 2 ·2H 2 O. The title complex has been characterized by elementary analysis, FT‐IR, UV‐Vis spectroscopy and x‐ray single crystal diffraction. The title complex crystallizes in the triclinic space group P1 with crystallographic data: a = 10.870(6) Å, b = 11.536(6) Å, c = 12.904(7) Å, α = 101.541(10)°, β = 110.573(9)°, γ = 99.441(9)°, V = 1435.2(13) Å 3 , Z = 1, D calcd = 1.350 g/cm 3 , F(000) = 615, R 1 = 0.0641, wR 2 = 0.1475. It displays one‐dimensional chain‐like structure formed by [K( cis‐syn‐cis‐ dicyclohexyl‐18‐crown‐6)] + complex cations and [Cu(mnt) 2 ] 2‐ complex anions through N‐K‐N interactions. Its electrochemical behavior has also been studied by the cyclic voltammetry. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
