Two new coordination polymers [Cd(tdc)(bpy)(H 2 O)] n ( 1 ) and [Cd(tdc)(phen)] n ( 2 ) (H 2 tdc = thiophene‐2,5‐dicarboxylic acid, bpy = 2,2′‐bipyridine and phen = 1,10‐phenanthroline) have been synthesized under hydrothermal condition. Their crystal structures have been established by X‐ray single‐crystal diffraction. Complex 1 crystallizes in the orthorhombic space group Fdd 2 with a = 14.757(7), b = 45.38(2), c = 10.518(5) Å, V = 7044(6) Å 3 , Z = 16; 2 in the monoclinic space group P 2 1 / c with a = 7.262(1), b = 21.970(2), c = 10.051(1) Å, β = 105.01(1)°, V = 1548.8(2) Å 3 , Z = 4. Both of them are double‐stranded chains and further assembled into three‐dimensional networks by π‐π stacking interactions. 1 and 2 are stable in air, and show blue photoluminescence at 415 nm and 410 nm, respectively.
