The one-pot hydrothermal reaction of CuCl2 with H2CPOA and 4,4＇-bpy results in two new coordination polymers, [Cu（CPOA）（4,4＇-bpy）（H2O）2]·1.5H2O （1） and [Cu2（HCPOA）4（4,4＇-bpy）4] （2） （H2CPOA=4-carboxyphenoxy acetic acid, 4,4＇-bpy=4,4＇-bipyridine） since CPOA^2- anions reach equilibrium with HCPOA^- anions in the reaction system. The crystal structure of 1 shows a triple interpenetration CdSO4-like net with 1D channel, in which lattice water molecules are located. Complex 2 is a ladder-like 1D double chain structure assembled through coordination bonds and O—H…N hydrogen bonds.
β-Co（OH）2 and Mg（OH）2 nanoplates were synthesized via a facile template-free hydrothermal approach.The different conditions of preparation and catalytic properties of the products were studied and discussed.The products were characterized by X-ray diffraction,transmission electron microscopy,scanning electron microscopy,selected area electron diffraction（SAED）,and gas chromatograph.
