A new 2D cobalt(II) coordination polymers namely [Co2(btec)(L)2]∙4H2O}n (1), where btec = 1,2,4,5-benzenetetracarboxylate and L = 1,3-bis(5,6-dimethylbenzimidazol-l-yl)-2-propanol, are hydrothermally synthesized and characterized by elemental analyses, IR spectroscopy, and single crystal X-ray diffraction analyses. The structure analysis indicates that the compound belongs to the triclinic system
