A new cobalt(Ⅱ)polymer with quasi-rectangular cavities,[Co(L)_2(TP)·H_2O]_n 1(L =1-butylbenzimidazole,TP=terephthalate ion)has been prepared by means of self-assembly of 1-butylbenzimidazole,terephthalic acid and Co(NO_3)_2·6H_2O.The structure of 1 was characterized by X-ray diffraction analysis.In the crystal packing,2-D supramolecular layers are formed viaπ-πstacking interactions.The fluorescence emission spectra of L and 1 are described.
