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 K2mnt and CuCl2.2H2O. 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 P-1 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) Å3, Z = 1, Dcalcd = 1.350 g/cm3, F(000) = 615, R1 = 0.0641, wR2 = 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.
