by CuII ions to form a 1D Cu–[Co2Mo10H4O38]6− inorganic chain, which is further linked by ligand L1 and [Co2Mo10H4O38]6− polyoxoanions, forming a 3D metal–organic framework. In complex 2, the adjacent [Co2Mo10H4O38]6− polyoxoanions link the CuII ions to generate a 2D Cu–[Co2Mo10H4O38]6− inorganic layer, which is further connected with bidentate ligands L2 to obtain a 3D metal–organic framework.
