N2 - The interaction of zerovalent copper with a proton-donating agent (NH4I) in acetonitrile solutions of CsX (X = Cl or I) and 18-crown-6 (18c6), in air, resulted in the formation of the novel mixed-metal complexes [Cs(18c6)2][Cu5I6(MeCN)2] 1, [Cs2(18c6)3][Cu8I10(MeCN) 2] 2 and [{Cs(18c6)}6Cu4I7][Cs3(18c6) 3][Cu7I10][Cu13I14]I 2 3. The main structural feature of the compounds is the multidecker sandwich Cs+-18c6 cations and finite iodocuprate(I) anions combined to form ionic lattices. It is proposed that the Cu+ oxidation state is stabilized in the presence of the Cs+-18c6 moieties in acetonitrile, and the overall formation of the solid phase is a template process of mutual stabilization of Cs+ as bulky [Csn(18c6)m]n+ cations and Cu+ as iodocuprate anions.
