Crystals of polymeric cerium(III) 1,2,3‐propanetricarboxylate dihydrate, [Ce(C 6 H 5 O 6 )(H 2 O) 2 ] n , were grown under hydrothermal conditions. The nine‐coordinate Ce atoms occur as centrosymmetric pairs. Two bidentate and three monodentate carboxylate groups, each from a different anion, and two water molecules are coordinated to each cerium ion. Ce—O distances range from 2.390 (3) to 2.637 (2) Å. Each anion is joined to five cerium ions, forming a three‐dimensional network.
