Tetranuclear Copper(I)-Based Infinite One-Dimentional Chain Complex. Synthesis and X-Ray Crystal Structure of {[Cu2(μ-3-methylpyridazine)2(μ-pyrazine)3](ClO4)2}∞

The title copper(I) compound has been isolated, whose X-ray crystallographic structure shows a rare polymerization mode in which the tetranuclear copper units, composed of three- and two-coordinate copper(I) atoms, are linked by pyrazines. This gives a cyclic voltammogram and a chrage transfer band characteristic of the polymeric structure in the solid state.
