By employing one bridging ligand, 2,4‐pyridinedicarboxylate (2,4‐pda 2− ), three one‐dimensional (1D) coordination polymers of [Cu(2,4‐pda)(H 2 O) 2 ] ∞ ( 1 ), {[Cu 4 (2,4‐pda) 4 (H 2 O) 8 ]·3H 2 O} ∞ ( 2 ), and {[Cd(2,4‐pda)(H 2 O) 3 ]·H 2 O} ∞ ( 3 ) were synthesized. A simple zigzag polymeric chain is observed for both 1 and 3 , but a railroad‐like zigzag polymeric chain is observed for 2. Almost all water molecules, whether coordinated or not, are involved in hydrogen bonding interactions and help to tie up the 1D polymeric chains of 1‐3 into a three‐dimensional (3D) network. A comparison about the coordination geometries in all similar coordination polymers available to date is also included.
