Crystal structure and electrochemical property of one-dimensional complex: [K(cis-syn-cis-dicyclohexyl-18-crown-6)](2)[Cu(mnt)(2)]

摘要

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 CuCl2 center dot 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 P (1) over bar with crystallographic data: a = 10.870(6) angstrom, b = 11.536(6) angstrom, c = 12.904(7) angstrom, alpha = 101.541(10)degrees, beta = 110.573(9)degrees, gamma = 99.441(9)degrees, V = 1435.2(13) angstrom(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. (c) 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
