A novel coordination polymer, [Co3 (bta)2(dib)2]·4H2O (1, H3bta=benzene-1,3,5-triacetic acid, and dib=1,4-di(1H-imidazol-1-yl)benzene), has been hydrothermally prepared and characterized by IR spectroscopy, elemental analysis and single-crystal X-ray diffraction. The crystal is of triclinic system, space group Pī, with a=9.141(2), b=9.667(2), c=13.855(2), α=100.83(3), β=90.81(3), γ=100.94(3)°, V=1179.0(4)3 , C48H46N8O16Co3 , Mr=1167.72, Dc=1.645 g/cm 3 , F(000)=599, μ=1.127 mm-1 and Z=1. The final R=0.0634 and wR=0.1703 for 4291 observed reflections (I > 2σ(I)). In the title complex, the bta ligand acts as a four-dentate bridging ligand to link up cobalt atoms into a lamellar framework, which are further interlinked by the dib ligands to generate a binodal (3,8)-connected tfz-d net.
