摘要：

Two cobalt(II) compounds, namely, {[Co(HL)(bpy)(H2O)(2)]center dot DMF}(n) (1), and {[Co(HL)(bpe)]center dot 0.5bpe}(n) (2) (H3L = 1,3-bis(2-carboxylphenoxy) benzoic acid, bpy = 4,4'-bipyridine, bpe = 4,4'-vinylenedipyridine), have been synthesized using cobalt(II) transition metal salt with phenolic carboxylic acid and different N-donor ligands. The compounds were fully characterized by elemental analysis, infrared spectroscopy (IR), single crystal X-ray diffraction analysis, and thermogravimetric analysis (TGA). Both compounds exhibit 2-D (4,4)-sql networks but with a wavelike and a double layered arrangement, respectively. Remarkably, these two compounds not only exhibit field-induced single-ion relaxation magnetization but also exceptional catalytic activities of benzylic C-H oxidation (conv. 90.3-99%; sele. 98.1-99%).
