We successfully synthesized a new cobalt(Ⅱ) coordination polymer under hydrothermal conditions,[Co(L)0.5(chdc)(H2O)]n(L=1,4-bis(thiabendazole)butane,H2 chdc=1,4-cyclohexanedicarboxylic acid),which were then characterized by elemental analyses,TG,IR spectroscopy and single-crystal X-ray diffraction.It crystallizes in the monoclinic system,space group P21/c with a =10.2855(12),b=9.3606(11),c=20.436(3) ?,β=91.573°,V=1966.8(4) ?3,Z=4,C20H22 Co N3O5S,Mr=475.40,Dc=1.605 g/cm3,μ=1.018 mm-1 and F(000)=984.The complex possesses a uninodal three-connected hcb Shubnikov hexagonal plane structure with {63} topology.These planes are further linked into a 3D supramolecular network via O-H···O hydrogen bonds involving coordinated water molecules and oxygen atoms of chdc2- ligands.The fluorescence and catalytic activities of the complex for degradation of Congo red in a Fenton-like process were investigated.

The complex possesses a uninodal three-connected hcb Shubnikov hexagonal plane structure with {63} topology.These planes are further linked into a 3D supramolecular network via OH ··· O hydrogen bonds containing coordinated water molecules and oxygen atoms of chdc2-ligands. The fluorescence and catalytic activities of the complex for degradation of Congo red in a Fenton-like process were investigated.
