✦ Synopsis

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 onedimensional 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.
