Abstract

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 La2CuO4, the antiferromagnetic molecular crystal with a (4,4) grid copper-formate framework Cu(HCOO)2(H2O)4 and its deuterated compound (Cu(DCOO)2(D2O)4) have been studied extensively for supposed dual-functional molecular crystals. The cover picture shows the ideal situation by replacing intercalated H2O with an organic donor. The organic-inorganic hybrid (BEDT-TTF)2Cu2(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 [(C2H5)3NH]2Cu2(HCOO)5 in a C6H5Cl-C2H5OH solution.
