Abstract: In the title one-dimensional coordination polymer, [Cd(-DPIA)₂(H₂O)]_n (DPIA^- is the 4,5-diphenylimidazole-1-acetate monoanion, C₁₇H₁₃N₂O₂), each Cd^II atom exists in a pentagonal-bipyramidal coordination geometry, defined by four O atoms and two N atoms from two DPIA^- ligands [Cd-O = 2.389 (4)-2.455 (4) Å and Cd-N = 2.362 (5)-2.372 (5) Å] and one water molecule [Cd-O(water) = 2.313 (2) Å]. Adjacent Cd^II ions are bridged by DPIA^- groups, forming an infinite chain structure. The CdCd separation within the polymer is 7.650 (3) Å. The structure is stabilized by weak hydrogen-bonding interactions.
