Abstract: Four transition metal coordination polymers {[Mn(2,4-Hoba)2(bipy)(H2O)2]·2H2O}n (1),[Mn(2,4-oba)(phen)]n (2),[Co(2,4-oba)(bimyb)0.5]n (3) and[Ni(2,4-oba)(bimyb)0.5]n (4) (2,4-H2oba=2,4-oxybis(benzoic acid), bipy=4,4'-bipyridine, phen=1,10-phenanthroline, bimyb=1,4-bis(imidazole-1-ylmethyl) benzene) were synthesized by hydrothermal reactions and characterized by single-crystal X-ray diffraction, thermogravimetric analyses, IR spectroscopy and elemental analysis. Complex 1 is a 1D chain structure, which is extended to a 2D supramolecular architecture by O-H…O hydrogen bonding. Complex 2 shows a 1D wavy chain structure, which is expanded to a 2D wavelike network through aromatic π-π stacking interactions. Complexes 3 and 4 are 2D layer structures produced by ligands bridging binuclear paddle-wheel units. The magnetic properties of 2~4 have also been investigated, and the exchange conpling constants were -0.79, -8.97 and -11.42 cm-1, respectively. According to the crystal structures, the magnetic coupling behavior of complexes 2~4 were studied by using hybrid DFT-BS method, and the result reveals that the calculated exchange coupling constants (J) are in good agreement with the experimental data. |
