A new inorganic-organic hybrid constructed from α-octamolybdate polyoxometalates modified by hexad- track Cu―bpe chains, 2{[Cu（bpe）]6[α-Mo8O26]3/2}·[Cu（bpe）]3·3H2O[1, bpe=bis（4-pyridyl）ethylene], has been synthesized and structurally characterized. X-Ray diffraction analysis reveals that each α-octamolybdate cluster links six transition metal complex chains and the title compound has represented the highest connective number of M―N chains modified octamolybdate POMs to date. Note that there are two crystallographically unique [α-Mo8O26]n- clusters and eight unique copper sites, which play an important role in the overall architecture of hybrid compounds. Additionally, the electrochemical properties of the title compound were studied.
