Реферат: A remarkable effect of solvents on the reaction outcome has been discovered in the synthesis of halocuprates, as exemplified by the reaction of CuI with 1-methyl-2-methylthiopyridinium iodide, (Me-PySMe)I. When performed in acetonitrile, the reaction results in the selective self-assembly of iodocuprate (Me-PySMe)(n)[Cu2I3](n) (1) featuring 1D double-stranded [Cu2I3](n) ribbons. Surprisingly, upon exploiting acetone as a medium under other conditions being similar, isomeric 1D iodocuprate 2 containing one-stranded [Cu2I3](n) chains is quantitatively formed. Iodocuprate 1 displays outstanding dual luminescence expressed by two emission bands at lambda(max) = 680 and 550 nm, probably originating from the excited states of the cluster-centered ((CC)-C-3) type and iodocuprate-to-cation charge transfer one, respectively. The resulting emission color of 1, being defined by the ratio of these bands, reversibly varies as a function of temperature spanning from deep-red (300 K) to yellow (77 K). Isomer 2, being also dual emissive, does not exhibit prominent thermochromic luminescence.
