N2 - A novel cobalt(II) coordination polymer, [Co(BTEC)1/2] n 1, has been synthesized with Co(NO3)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 5HO4Co, Mr = 183.99, monoclinic, space group C2/c, a = 16.619(6), b = 7.416(3), c = 8.040(3) Å, β = 90.612(4)°, V= 990.8(6) Å3, Z = 8, Dc = 2.467 g/cm3, β = 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(410.614.84) topology.
