Abstract
Treatment of CuI with PhSCH~2~SPh in MeCN solution affords, by a self‐assembly reaction, the monodimensional metal–organic coordination polymer [Cu~4~I~4~{μ‐PhS~2~CH~2~SPh}~2~]~n~ (1), in which Cu~4~(μ^3^‐I)~4~ cluster units are linked by the dithioether ligand in a 1D necklace structure. In contrast, the reaction of PhSCH~2~CH~2~SPh with CuI results in the formation of the metallopolymer [(CuI)~2~{μ‐PhS(CH~2~)~2~SPh}~2~]~n~ (2). The 2D network of 2 is built from dimeric Cu~2~I~2~ units which are connected by 1,2‐bis(phenylthio)ethane bridging ligands. The solid‐state luminescence spectrum of 1 exhibits a strong emission around 532 nm, whereas a weak emission centred at 413 nm is observed in the case of 2. (© Wiley‐VCH Verlag GmbH & Co.
