Abstract

Reaction of 2-(methylthio)pyrazine (L) with CuI (MeCN, r.t.) results in formation of iodide-bridged complex [Cu22-I)2L4], wherein Cu⋯Cu contact of 2.6351(4) Å is observed. The each metal atom of the [Cu22-I)2] core is coordinated by the two ligands via 4-pyrazyl nitrogen atoms. In the solid state at room temperature, the complex obtained emits an orange photoluminescence (λmax = 600 nm) with the average lifetime of 1.66 μs and quantum yield of 17%.
