A novel imidazo[1,2‐ a ]pyridin‐2‐one ligand, 3,3‐bis(carboxymethyl)imidazo[1,2‐ a ]pyridin‐2‐one (H 2 L), was conveniently synthesized and acts as a three‐connecting T‐shaped building block. Hydrothermal treatment of the H 2 L ligand with Cd(ClO 4 ) 2 · 6H 2 O or Zn(ClO 4 ) 2 · 6H 2 O gives two new coordination polymers, [CdL(H 2 O) 2 ] n ( 1 ) or [ZnL(H 2 O)] n ( 2 ). Compound 1 consists of a rare 1D ladder‐like chain and 2 is the first example of a polymer with a 2D basket weave network. Solid‐state photoluminescent analyses of 1 and 2 show that they display strong fluorescent emissions. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
