The self-assembly of terephthalic acid, triethylenediamine and Cd(NO3)(2)center dot 4H(2)O under solvothermal condition gave one 2D cadmium coordination polymer, {Cd(bdc)(dabco)(DMF)]center dot 2H(2)O}(n) (1) (bdc=terephthalate, dabco=triethylenediamine), which has been characterized by elemental analysis, IR, TGA and single-crystal X-ray diffraction. The bdc ligands linked the Cd(II) centers to form an infinite Cd-carboxylate chain. The chains are further bridged by dabco ligands, forming a two-dimensional layered network. Interestingly, 2D layered network contains small channels of 0.74 nmx0.65 nm along the c axis. The photoluminescence and lifetime of 1 in the solid state have been studied. CCDC: 847762.
