Abstract
The title complex, [Eu(C6H4O2)(3)(H2O)(2)], has a double carboxylate-bridge d infinite-chain structure, with one chelating carboxylate group on each Eu ion centre, which also binds to two water molecules to yield an eight-coor dinate square-antiprismatic geometry, with Eu-O bond lengths in the range 2 .338 (3)-2.594 (3) Angstrom. The pyridine N atoms of the isonicotinate grou ps do not coordinate to the Eu ions; instead, they direct the formation of Eu III coordination polymers via hydrogen bonding with coordinated water mo lecules.
