| 摘 要： | A novel cobalt（II） coordination polymer,[Co（BTEC）1/2]n 1,has been synthesized with Co（NO3）2·6H2O and 1,2,4,5-benzenetetracarboxylic acid （H4BTEC） by the hydrothermal method,and characterized by elemental analysis,IR and single-crystal X-ray diffraction. Crystallographic data for 1： C5HO4Co,Mr = 183.99,monoclinic,space group C2/c,a = 16.619（6）,b = 7.416（3）,c = 8.040（3）A,β = 90.612（4）°,V = 990.8（6） A^3,Z = 8,Dc = 2.467 g/cm^3,μ = 3.390 mm^-1,F（000） = 720,R = 0.0307 and wR = 0.0847 for 912 observed reflections （I 〉 2σ（I））. X-ray crystal structural analysis revealed that each Co（II） adopts a tetrahedral coordination mode to link four separate BTEC ligands via uniform monodentate carboxylate groups and each BTEC ligand possesses an 8-connected geometry to connect eight Co（II） ions. Complex 1 exhibits a rare （4,8）-connected net with （45.6）2（410.614.84） topology.

| Abstract: | A novel cobalt(II) coordination polymer, [Co(BTEC)_(1/2)]_n 1, has been synthesized with Co(NO_3)_2·6H_2O and 1,2,4,5-benzenetetracarboxylic acid (H4BTEC) by the hydrothermal method, and characterized by elemental analysis, IR and single-crystal X-ray diffraction. Crystallographic data for 1: C_5HO_4Co, M-r = 183.99, monoclinic, space group C2/c, a = 16.619(6), b = 7.416(3), c = 8.040(3) (A), β = 90.612(4)°, V= 990.8(6) (A)~3, Z = 8, D_c = 2.467 g/cm~3, μ = 3.390 mm~(-1), F(000) - 720, R = 0.0307 and wR = 0.0847 for 912 observed reflections (I > 2σ(I)). X-ray crystal structural analysis revealed that each Co(II) adopts a tetrahedral coordination mode to link four separate BTEC ligands via uniform monodentate carboxylate groups and each BTEC ligand possesses an 8-connected geometry to connect eight Co(II) ions. Complex 1 exhibits a rare (4,8)-connected net with (4~5.6)_2(4~(10).6~(14).8~4) topology. |
