3D framework constructed from Keggin polymolybdate anion covalently linked by meso-helical mixed-valence copper(I/II) complex

A new inorganic-organic hybrid [{CuII(pda)(H2O)Cu2I(bpy)3}{GeMo12O40]n·2nH2O was synthesized by hydrothermal method and its structure was determined by X-ray crystallography. The copper(I/II) complex located in 1 shows an unusual meso-helical chain structure, showing synergetic electrochemical and luminescence properties.
