(BEDT‐TTF)(2)Cu(2)(HCOO)(5): An Organic–Inorganic Hybrid Conducting Magnet

This month's cover picture results from Professor Bin Zhang's collaborative work between Chinese Academy of Sciences and Peking University (China). Since the discovery of high‐temperature superconductors for hole doping on parent antiferromagnetic compound La(2)CuO(4), the antiferromagnetic molecular crystal with a (4,4) grid copper‐formate framework Cu(HCOO)(2)(H(2)O)(4) and its deuterated compound (Cu(DCOO)(2)(D(2)O)(4)) have been studied extensively for supposed dual‐functional molecular crystals. The cover picture shows the ideal situation by replacing intercalated H(2)O with an organic donor. The organic–inorganic hybrid (BEDT‐TTF)(2)Cu(2)(HCOO)(5) is obtained through the electrochemical oxidation of neutral BEDT‐TTF in the presence of an ammonium salt of the 1D copper‐formate framework [(C(2)H(5))(3)NH](2)Cu(2)(HCOO)(5) in a C(6)H(5)Cl‐C(2)H(5)OH solution.
