catena-Poly[[aqua­[3-(3-pyrid­yl)acrylato]gadolinium(III)]-bis­[μ-3-(3-pyrid­yl)acrylato]]

In the title compound, [Gd(C8H6NO2)3(H2O)]n, the gadolinium(III) ion is coordinated by eight carboxyl­ate O atoms and one water mol­ecule. The carboxyl­ate ligands bridge pairs of gadolinium(III) ions, forming a zigzag chain along [100]. Hydrogen bonds link the chains into sheets parallel to (001).
